Also I tried Windows Update from a Windows 2000 machine just now and although it appears to be working, all is not well because it reports "There are no updates available for your computer" when I know full well that it normally keeps insisting that I install the .NET stuff and Media player 9. (And a few other things under the windows section that I normally refuse to install) Perhaps MS have temporarily suspended downloading of "non critical" updates to reduce the server load from people who go to windows update primarily to get the security related updates....

You're correct. We never used windowsupdate.com for anything, none of our stuff points to it at all - it was only a redirect site. There was a redirect in place going from windowupdate.com to windowsupdate.microsoft.com up until about 9pm NZ time last night.

APE route servers
by Andy Linton 15 Aug '03

15 Aug '03

Those of you who use our route servers should use the Looking Glass at http://www.wix.net.nz/cgi-bin/mrlg-ape.cgi to check that you are peering with both route servers. Some of you have a session with rs1 but not with rs2. It would make sense for you to add the second server for redundancy. The configuration details are identical apart from the IP address of the BGP peer. 192.203.154.2 instead of 192.203.154.1.

ISPs / Sites blocking IPs?

All I'm on a TelstraClear / paradsie cable modem. When I try to access the web site for the "Indepednent" in the UK, I get: Access Denied You don't have permission to access "http://news.independent.co.uk/uk/environment/story.jsp?" on this server.

RE: [nznog] Re:Domain Name Scams
by Paul Adshead 10 Aug '03

10 Aug '03

It is to be fair, incredibly simple to find out most of the information regarding the allocation of a domain. Just go to the main DomaiNZ page: www.domainz.net.nz and enter your (NZ) domain name into the search box on the left. After selecting OK, then a warning about not being able to use this information for any other purpose appears - and this warning automatically disappears after a few seconds anyway. After this, then all of the details for the queried domain appear! As the warning message automatically disappears, then the content of the warning is probably not legally enforceable anyway - you could have been looking away from your screen at that point! They should have a "Yes I've read the above agreement" checkbox before you can proceed... Possible ways that the scam has found out the contact info: - if you knew enough about HTML, ASP and VB, it would be simple enough to write a program that once every five seconds sent a request to the DomaiNZ webserver starting at "a.co.nz" and finishing at "zzzzzzz999.net.nz", to find out the information for the various domains - it would take a while though; - you could use an 'electronic dictionary' of words in order to cut down on the unlikely examples; - there is also probably an online listing somewhere, of all of the currently active companies in New Zealand, you could then just try "<company name>.co.nz" and "<company name>.net.nz". There are far too many ways that people could have done it. I'm not condoning what has happened and have not done so myself, I'm just trying to explain how easy it is to do so. I was hit with three renewals too...

It only disappears when the page reloads with the results. It's only a GUI'd representation of a WhoIs query. On registration, there is a physical need to click a "I've read the terms of service" button, but at the end of the day, any information entered as part of a domain name registration is available in the public domain.

The company "DomianNamesNZ" is actually "Domain Names Australia Pty Limited" a Australian based company incorporated in Victoria. They also go by "Internet Registry Pty Limited" and "NetRegister" (Not NetRegistry). The address they're using, the ASB tower in Auckland is an internet bought mail forwarding address. They have also done mail-outs and fax-outs in Australia - http://www.auda.org.au/about/news/2003061903.html One thing interesting is that they have sent letters to customers of Internet Name Group (ING) who did a similar mail-out in NZ in a while back, the letters were filled with B.S and obviously asked they register renew domains with them.

TelstraClear Routing?
by Steve Withers 07 Aug '03

07 Aug '03

I've been using a VPN to connect to work across the WIX for over a year - via a Paradise cable modem. I was seeing about 1mbps throughput, consistent with AT&T's Wellington Office (the actual people-at-desks office) United Networks connection to the WIX. A traceroute showed roughly 5-6 hops as I recall. Today....I can't get my VPN tunnel up at all and the traceroute shows 15 hops and my traffic is going to Auckland and off to Reach in HongKong...and then into AT&T's network there and then back again via Australia to NZ. Is anyone else seeing similar routing troubles? -- Steve Withers <swithers(a)mmp.org.nz>

I've been getting a few good old snail mail letters from Domainnamesnz.com offering me to register domain names. Eg: I own learnbydestroying.co.nz and the "offer" is for learnbydestroying.net . How ever since these letters include; Reference #, MPID ? , Closing Date, Credit card details, and very little info to conclude that this is a Renewal many people have inadvertently paid the money ( $237 for two years ! ) thinking it's a Domainz or other registrar invoice. I'm not questioning the legality of this , as I am no expert, how ever im interested to know how so many of my clients and myself ended up with these letters? Anyone else experienced these letters or perhaps had clients pay for what they thought was a valid renewal?

It's not an old one and they didn't get it from Domainz. One of the domains I got a note about was only registered a few months ago via Freeparking. As an aside, this will work on some people. My wife (who is not unclueful) was opening the mail, handed me the nonvoices and said "Bills from Domainz. Do you want me to pay them online?"

Thanks to all that responded to Andy's plea, on my behalf, for a 2500 series power supply. I've managed to find a supplier in NZ - a list member - and it should be here in a couple of weeks. In the meantime we got the box running per the solution at http://www.hardstaff.com/Computer/Cisco/index.html and it's been working for about a week now with no apparent problems. Cheers, Jon

IP to PSTN/Public network gateway.
by Gavin Legge [Invincible Technologies Limited NZ] 05 Aug '03

05 Aug '03

First question from a new list member (probably go straight to FAQ no?).... Does anyone know of a (preferably) New Zealand based provider that provides an 'IP' to 'public network' and back again gateway service (at a charge or otherwise)? Somewhere we can fire IP voice calls at, that will take the IP voice call and poke it out to the local number, local number being a normal everyday phone connected to the PSTN ? Thanks for any advice Regards Gavin Legge

I currently have an IPExpress circuit from TelstraClear providing Internet access. I'd like to be able to have staff use some kind of fast IP service (ie ADSL), to connect in to the office to do thier work, I don't want Internet access over these links, just some form of nationally accessable 'VPN'. It only needs to be 1-2Mbit speed, but can't complain if its more. Is this kind of thing being done? I tried to contact Telecom about it only to have some customer support monkey tell me that ADSL is an Internet thing, and as much as I love dealing with support people...

Performance issues on Citylink yesterday (Saturday Jul 19)
by Simon Blake 19 Jul '03

19 Jul '03

Our apologies to the folks who suffered from performance problems on Citylink yesterday (Saturday). They were caused by an ISP under apparent SYN attack - not in itself a particularly unusual occurence, what was interesting was that in changes on Saturday morning (about 3am) said ISP managed to make the IP address under attack an unfiltered broadcast address on Citylink, so we all got to share the pain of a kind of combo SYN/smurf attack. The attacks manifested as 8-10Mb/s streams coming from the ISP onto Citylink for 1-4 minutes, about twice every two hours, which in turn caused some 10Mb customers on Citylink some disruption of service - 100Mb/1Gb customers seemed to be largely unaffected. The short duration and occasional nature of the problem did cause a few issues with tracking it and getting a resolution (about 9pm last night) - again, our apologies for not getting it sorted faster. Cheers Si

exploits logged in Auckland
by Joe Abley 17 Jul '03

17 Jul '03

I have seen attempts to exploit the recently-announced cisco vuln on a router of my acquaintance in Auckland, starting early this morning NZST. This confirms the notes on nanog (and in the updated cisco advisory) about functional exploits being published and used in the wild. The source addresses appear spoofed, and so far all of the hits have been received from outside NZ. The address "x.x.x.114" (see below) isn't in use on a router or anywhere else. Presumably the k1dd13z will realise at some point that there is more dead air on the Internet than ciscos, and will start harvesting victim addresses from traceroute instead of choosing them randomly. Is anybody contemplating customer-facing filters which block protocols 53, 54, 77 and 103?

Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packet
by Rob Thomas 17 Jul '03

17 Jul '03

FYI. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty); -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packet Revision 1.3 ============ Last Updated 2003 July 17 at 23:00 UTC (GMT) For Public Release 2003 July 17 at 6:10 UTC (GMT) ================= - ---------------------------------------------------------------------- Please provide your feedback on this document. - ---------------------------------------------------------------------- Contents ======== Summary Affected Products Details Impact Software Versions and Fixes Obtaining Fixed Software Workarounds Exploitation and Public Announcements Status of This Notice: INTERIM Distribution Revision History Cisco Security Procedures - ---------------------------------------------------------------------- Summary ======= Cisco routers and switches running Cisco IOS� software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets with specific protocol fields sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available. Cisco has made software available, free of charge, to correct the problem. This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml. Affected Products ================= This issue affects all Cisco devices running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets. Cisco devices which do not run Cisco IOS software are not affected. Devices which run only Internet Protocol version 6 (IPv6) are not affected. Details ======= Cisco routers are configured to process and accept Internet Protocol version 4 (IPv4) packets by default. A rare, specially crafted sequence of IPv4 packets with protocol type 53 (SWIPE), 55 (IP Mobility), 77 (Sun ND), or 103 (Protocol Independent Multicast - PIM) which is handled by the processor on a Cisco IOS device may force the device to incorrectly flag the input queue on an interface as full, which will cause the router to stop processing inbound traffic on that interface. This can cause routing protocols to drop due to dead timers. Interfaces which are explicitly configured to run PIM will not be affected by traffic with protocol type 103. An interface with PIM enabled will have one of the following three commands in the interface configuration: ip pim dense-mode, ip pim sparse-mode, or ip pim sparse-dense-mode. On Ethernet interfaces, Address Resolution Protocol (ARP) times out after a default time of four hours, and no traffic can be processed. The device must be rebooted to clear the input queue on the interface, and will not reload without user intervention. The attack may be repeated on all interfaces causing the router to be remotely inaccessible. A workaround is available, and is documented in the Workarounds section. The following two Cisco vulnerabilities are documented in DDTS: CSCea02355 ( registered customers only) affects all Cisco routers running Cisco IOS software. This documents the flaw with protocols 53, 55, and 77. CSCdz71127 ( registered customers only) was introduced by an earlier code revision, and documents an input queue vulnerability to protocol 103 with a device which is not configured for PIM. Any version of software which has the fix for CSCdx02283 ( registered customers only) is vulnerable. Registered customers can find more details using the Bug Toolkit at http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl ( registered customers only) . To identify a blocked input interface, use the show interfaces command and look for the Input Queue line. If the current size (in this case, 76) is larger than the maximum size (75), the input queue is blocked. Use the show buffers command and look for the prot field. Below are two examples: Router#show interface ethernet 0/0 Ethernet0/0 is up, line protocol is up Hardware is AmdP2, address is 0050.500e.f1e0 (bia 0050.500e.f1e0) Internet address is 172.16.1.9/24 MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec) ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:41, output 00:00:07, output hang never Last clearing of "show interface" counters 00:07:18 Input queue: 76/75/1091/0 (size/max/drops/flushes); Total output drops: 0 !--- The 76/75 shows that this is blocked Router#show buffers input-interface serial 0/0 Buffer information for Small buffer at 0x612EAF3C data_area 0x7896E84, refcount 1, next 0x0, flags 0x0 linktype 7 (IP), enctype 0 (None), encsize 46, rxtype 0 if_input 0x6159D340 (FastEthernet3/2), if_output 0x0 (None) inputtime 0x0, outputtime 0x0, oqnumber 65535 datagramstart 0x7896ED8, datagramsize 728, maximum size 65436 mac_start 0x7896ED8, addr_start 0x7896ED8, info_start 0x0 network_start 0x7896ED8, transport_start 0x0 source: 212.176.72.138, destination: 212.111.64.174, id: 0xAAB8, ttl: 41, prot: 103 !--- prot: 103 is proof that this is one of the attack packets Impact ====== A device receiving these specifically crafted IPv4 packets will force the inbound interface to stop processing traffic. The device may stop processing packets destined to the router, including routing protocol packets and ARP packets. No alarms will be triggered, nor will the router reload to correct itself. This issue can affect all Cisco devices running Cisco IOS software. This vulnerability may be exercised repeatedly resulting in loss of availability until a workaround has been applied or the device has been upgraded to a fixed version of code. Software Versions and Fixes =========================== Each row of the table describes a release train and the platforms or products for which it is intended. If a given release train is vulnerable, then the earliest possible releases that contain the fix and the anticipated date of availability for each are listed in the Rebuild, Interim, and Maintenance columns. In some cases, no rebuild of a particular release is planned; this is marked with the label "Not scheduled." A device running any release in the given train that is earlier than the release in a specific column (less than the earliest fixed release) is known to be vulnerable, and it should be upgraded at least to the indicated release or a later version (greater than the earliest fixed release label). When selecting a release, keep in mind the following definitions: * Maintenance Most heavily tested and highly recommended release of any label in a given row of the table. * Rebuild Constructed from the previous maintenance or major release in the same train, it contains the fix for a specific vulnerability. Although it receives less testing, it contains only the minimal changes necessary to effect the repair. Cisco has made available several rebuilds of mainline trains to address this vulnerability, but strongly recommends running only the latest maintenance release on mainline trains. * Interim Built at regular intervals between maintenance releases and receives less testing. Interims should be selected only if there is no other suitable release that addresses the vulnerability, and interim images should be upgraded to the next available maintenance release as soon as possible. Interim releases are not available through manufacturing, and usually they are not available for customer download from CCO without prior arrangement with the Cisco Technical Assistance Center (TAC). In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco TAC for assistance, as shown in the section following this table. +--------------------------------------------------------------------+ |Train |Description of |Availability of Fixed Releases | | |Image or Platform | | |--------------------------+-----------------------------------------+ | 11.x based releases | Rebuild |Interim| Maintenance | |--------------------------+-----------+-------+---------------------+ |11.1CA| |11.1(36)CA4| | | | | |** | | | |------+-------------------+-----------+-------+---------------------+ |11.2 | |11.2(26e)**| | | |------+-------------------+-----------+-------+---------------------+ |11.2P | |11.2(26)P5*| | | | | |* | | | |------+-------------------+-----------------------------------------+ |11.3 | |Not scheduled | |------+-------------------+-----------------------------------------+ |11.3T | |Not scheduled | |--------------------------+-----------------------------------------+ |12.0 based releases |Rebuild |Interim|Maintenance | |--------------------------+-----------+-------+---------------------+ | |General Deployment | | | | |12.0 |release for all | | |12.0(26) | | |platforms | | | | |------+-------------------+-----------------------------------------+ |12.0DA|xDSL support: 6100,|Migrate to 12.2DA; 12.2(10)DA2 - | | |6200 |Aug-15-2003, 12.2(12)DA3 - Aug-22-2003: | | | |Engineering Specials available on | | | |request. | |------+-------------------+-----------------------------------------+ |12.0DB|Early Deployment |Migrate to 12.3(1a) | | |6400 UAC for NSP | | |------+-------------------+-----------------------------------------+ |12.0DC|Early Deployment |Migrate to 12.3(1a) | | |6400 UAC for NRP | | |------+-------------------+-----------------------------------------+ | | |12.0(24)S2 | | | | | |12.0(23)S3 | | | | | |12.0(22)S5 | | | | | |12.0(21)S7 | | | | | |12.0(19)S4 | | | | |Core/ISP support: |12.0(18)S7 | | | |12.0S |GSR, RSP, c7200, |12.0(17)S7 | |12.0(25)S | | |c10k |12.0(16)S10| | | | | |12.0(15)S7 | | | | | |12.0(14)S8 | | | | | |12.0(13)S8 | | | | | |12.0(12)S4 | | | | | |12.0(10)S8 | | | |------+-------------------+-----------------------------------------+ |12.0SC|Cable/broadband |Migrate to 12.1(19)EC | | |ISP: ubr7200 | | |------+-------------------+-----------------------------------------+ |12.0SL|100000 ESR:c10k |Migrate to 12.0(23)S3, **12.0(17)SL9 - | | | |Jul-15-2003 | |------+-------------------+-----------------------------------------+ |12.0SP|Early Deployment |Migrate to 12.0(22)S5 | |------+-------------------+-----------------------------------------+ | |Early Deployment |12.0(21)ST7| | | |12.0ST|release for Core/ |12.0(20)ST6| | | | |ISP support: GSR, |12.0(19)ST6| | | | |RSP, c7200 |12.0(17)ST8| | | |------+-------------------+-----------------------------------------+ |12.0SX|Early Deployment |Migrate to 12.0(22)S5 | |------+-------------------+-----------------------------------------+ |12.0SY|Early Deployment |Migrate to 12.0(23)S3 | |------+-------------------+-----------------------------------------+ |12.0SZ|Early Deployment |Migrate to 12.0(23)S3 | |------+-------------------+-----------------------------------------+ |12.0T |Early Deployment |12.0(7)T3**| | | |------+-------------------+-----------+-------+---------------------+ | |8510c, ls1010, | | |12.0(26)W5(28) | | |cat8540c,cat8540m, | | | | | |ls1010 | | | | | |-------------------+-----------+-------+---------------------+ | |c5atm |12.0(26)W5 | | | | | |(28a) | | | | |-------------------+-----------+-------+---------------------+ | |Cat4232 and |12.0(25)W5 | | | |12.0W5|Cat2948G-L3 |(27) | | | | |-------------------+-----------+-------+---------------------+ | |C6MSM |Engineering| | | | | |Special | | | | | |available | | | | | |on request | | | | |-------------------+-----------+-------+---------------------+ | |c5rsfc,c5rsm,C3620,| | |12.1(20) | | |C3640, C4500, | | | | | |C7200, RSP | | | | |------+-------------------+-----------+-------+---------------------+ |12.0WC|Early deployment |12.0(05)WC8| | | | |2900XL-LRE,2900XL/ | | | | | |3500XL; 2950 | | | | | |release | | | | |------+-------------------+-----------+-------+---------------------+ |12.0WT|Early deployment |Engineering| | | | |Catalyst switches: |Special | | | | |cat4840g, |Available | | | | | |upon | | | | | |request | | | |------+-------------------+-----------------------------------------+ |12.0X |Shortlived Early |All 12.0X(any letter) releases have | |(l) |Deployment Releases|migrated to either 12.0T or 12.1 unless | | | |otherwise documented in the X release | | | |technical notes pertaining to the | | | |specific release.

Please contact the Cisco TAC and request the specific images you need posted. Obtaining Fixed Software ======================== Customers with contracts should obtain upgraded software free of charge through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on the Cisco worldwide website at http://www.cisco.com/tacpage/sw-center/sw-ios.shtml. Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for assistance with obtaining the free software upgrade(s). Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac(a)cisco.com Please have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC. Please do not contact either "psirt(a)cisco.com" or "security-alert(a)cisco.com" for software upgrades. See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including special localized telephone numbers, instructions, and e-mail addresses for use in various languages. Workarounds =========== AFTER APPLYING THE WORKAROUND the input queue depth may be raised with the hold-queue <new value> in interface command -- the default size is 75. This will allow traffic flow on the interface until the device can be reloaded. Cisco recommends that all IOS devices which process IPv4 packets be configured to block traffic directed to the router from any unauthorized source with the use of Access Control Lists (ACLs). This can be done at multiple locations, and it is recommended that you review all methods and use the combination which fits your network best. Legitimate traffic is defined as management protocols such as telnet, snmp or ssh, and configured routing protocols from explicitly allowed peers. All other traffic destined to the device should be blocked at the input interface. Traffic entering the network should also be carefully evaluated and filtered at the network edge if destined to an infrastructure device. Although network service providers must often allow unknown traffic to transit their network, it is not necessary to allow that same traffic destined to their network infrastructure. Several white papers have been written to assist in deploying these recommended security best practices. ACLs can have performance impact on certain platforms, so care should be taken when applying the recommended workarounds. Transit ACLs The following access list is specifically designed to block attack traffic. Note that the attack traffic can include spoofed source addresses. This access list should be applied to all interfaces of the device, and should include topology-specific filters. This could include filtering routing protocol traffic, management protocols, and traffic destined for the internal network. Protocol 103 is Protocol Independent Multicast (PIM), which is a commonly deployed application in multicast networks. Interfaces with PIM enabled have not been found to be vulnerable to exploit traffic with protocol 103; PIM traffic may be permitted to those select devices. access-list 101 deny 53 any any access-list 101 deny 55 any any access-list 101 deny 77 any any access-list 101 deny 103 any any !--- insert any other previously applied ACL entries here !--- you must permit other protocols through to allow normal !--- traffic -- previously defined permit lists will work !--- or you may use the permit ip any any shown here access-list 101 permit ip any any Prior to deploying ACLs that filter transit traffic, a classification ACL can be used to help identify required permit statements. A classification ACL is an ACL that permits a series of protocols. Displaying access-list entry hit counters helps determine required protocols: entries with zero packets counted are likely not required. Classification access-lists are detailed in the link below for infrastructure access-lists. Receive ACLs For distributed platforms, receive path access lists may be an option starting in Cisco IOS Software Versions 12.0(21)S2 for the c12000 and 12.0(24)S for the c7500. The receive access lists protect the device from harmful traffic before the traffic can impact the route processor. The CPU load is distributed to the line card processors and helps mitigate load on the main route processor. The white paper entitled "GSR: Receive Access Control Lists" will help you identify and allow legitimate traffic to your device and deny all unwanted packets: http://www.cisco.com/warp/customer/707/racl.html Infrastructure ACLs Although it is often difficult to block traffic transiting your network, it is possible to identify traffic which should never be allowed to target your infrastructure devices and block that traffic at the border of your network. The white paper entitled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection ACLs: http://www.cisco.com/warp/customer/707/iacl.html Exploitation and Public Announcements ===================================== Since the initial posting of this document, the Cisco PSIRT has been made aware of public announcements of the vulnerabilities described in this advisory.

IPv6

Hey, I was just looking through the archives of the list, and found a post that was about IPv6 peering in New Zealand. I am currently trying to setup a website (http://www.ipv6.co.nz) but as such, I am the only one involved :P. If anyone wants to help me setup content for the site etc, or if you would like to use the domain for such things as the domain for a New Zealand IPv6 Peer... then by allmeans... you can use it, just email me...

Don't know how many windows admins out there, but incase you havn't yet heard about the new windows RPC sploit, read below. ----- Forwarded message from Haroon Meer <haroon(a)sensepost.com> ----- Date: Fri, 18 Jul 2003 02:48:06 +0200 (SAST) From: Haroon Meer <haroon(a)sensepost.com> Reply-To: Haroon Meer <haroon(a)sensepost.com> Subject: Critical Vulnerability discovered in Windows Servers To: icepick(a)cybernett.co.za Dear Barry Murphy, Vulnerability in Microsoft Windows Servers. Versions Affected : Windows XP, Windows NT4, Windows2000, Windows2003 Severity of Bug : CRITICAL Port / Service : Port 135 - Microsoft RPC A Polish security research group have found a remotely exploitable bug in Windows based operating systems. The bug affects almost the entire Microsoft Product range from Windows NT4, to Windows2000 and even Windows2003. The exploit uses port 135 as its attack vector with the exploitable component being Microsoft RPC. This vulnerability should be considred "Critical" since it yields "SYSTEM" privileges on the victim machine. Microsoft have issued an advisory and a patch is available from them at the following location : http://www.microsoft.com/security/security_bulletins/ms03-026.asp The possible workarounds for the problem untill the patch is applied are to : [a] Firewall off access to port 135 [b] Disable DCOM on the server (Using Dcomcnfg.exe) While no exploit code for this vulnerability is currently reported in the wild, the problem aknowledged by Microsoft to be exploitable, meaning that Proof of Concept exploits (and possibly worms) will not be a long time coming. Full details on the exploit can be found at http://lsd-pl.net/special.html.

At the nznog meeting in Auckland last week I said I'd give details of how to apply for a connection once the new web pages were available and so here they are: http://www.citylink.co.nz/cgi-bin/wixape.pl?tmpl=ape.tmpl http://www.citylink.co.nz/cgi-bin/wixape.pl?tmpl=wix.tmpl You may also find the two Looking Glass pages, that give a view of what is happening on the APE and WIX route servers, useful: http://www.wix.net.nz/cgi-bin/mrlg-ape.cgi http://www.wix.net.nz/cgi-bin/mrlg-wix.cgi
