I have been told that my quintum is failing because of a virus that
has penetrated Quintum gateways and attacks(?) through ports 1718,
1719, and 1720. As a result the gateway is having to be reset every
time the traffic starts to pick up. Also, blocking those ports
through the firewall doesn't seem to help. Has anyone experienced
this lately or does this make sense? It happened to me this morning
and has been a thorn in my side all day and I have a felling a couple
of more days to come.

CERT Advisory CA-2004-01 Multiple H.323 Message Vulnerabilities

Original release date: January 13, 2004
Last revised: --
Source: CERT/CC, NISCC

A complete revision history can be found at the end of this file.

Systems Affected

* Many software and hardware systems that implement the H.323
protocol

Examples include
+ Voice over Internet Protocol (VoIP) devices and software
+ Video conferencing equipment and software
+ Session Initiation Protocol (SIP) devices and software
+ Media Gateway Control Protocol (MGCP) devices and software
+ Other networking equipment that may process H.323 traffic
(e.g., routers and firewalls)

Overview

A number of vulnerabilities have been discovered in various
implementations of the multimedia telephony protocol H.323. Voice over
Internet Protocol (VoIP) and video conferencing equipment and software
can use these protocols to communicate over a variety of computer
networks.

I. Description

The U.K. National Infrastructure Security Co-ordination Centre (NISCC)
has reported multiple vulnerabilities in different vendor
implementations of the multimedia telephony protocol H.323. H.323 is
an international standard protocol, published by the International
Telecommunications Union, used to facilitate communication among
telephony and multimedia systems. Examples of such systems include
VoIP, video-conferencing equipment, and network devices that manage
H.323 traffic. A test suite developed by NISCC and the University of
Oulu Security Programming Group (OUSPG) has exposed multiple
vulnerabilities in a variety of implementations of the H.323 protocol
(specifically its connection setup sub-protocol H.225.0).

Information about individual vendor H.323 implementations is available
in the Vendor Information section below, and in the Vendor Information
section of NISCC Vulnerability Advisory 006489/H323.

The U.K. National Infrastructure Security Co-ordination Centre is
tracking these vulnerabilities as NISCC/006489/H.323. The CERT/CC is
tracking this issue as VU#749342. This reference number corresponds to
CVE candidate CAN-2003-0819, as referenced in Microsoft Security
Bulletin MS04-001.

II. Impact

Exploitation of these vulnerabilities may result in the execution of
arbitrary code or cause a denial of service, which in some cases may
require a system reboot.

III. Solution

Apply a patch or upgrade

Appendix A and the Systems Affected section of Vulnerability Note
VU#749342 contain information provided by vendors for this advisory
(<http://www.kb.cert.org/vuls/id/749342#systems>).

However, as vendors report new information to the CERT/CC, we will
only update VU#749342. If a particular vendor is not listed, we have
not received their comments. Please contact your vendor directly.

Filter network traffic

Sites are encouraged to apply network packet filters to block access
to the H.323 services at network borders. This can minimize the
potential of denial-of-service attacks originating from outside the
perimeter. The specific services that should be filtered include

* 1720/TCP
* 1720/UDP

If access cannot be filtered at the network perimeter, the CERT/CC
recommends limiting access to only those external hosts that require
H.323 for normal operation. As a general rule, filtering all types of
network traffic that are not required for normal operation is
recommended.

It is important to note that some firewalls process H.323 packets and
may themselves be vulnerable to attack. As noted in some vendor
recommendations like Cisco Security Advisory 20040113-h323 and
Microsoft Security Bulletin MS04-001, certain sites may actually want
to disable application layer inspection of H.323 network packets.

Protecting your infrastructure against these vulnerabilities may
require careful coordination among application, computer, network, and
telephony administrators. You may have to make tradeoffs between
security and functionality until vulnerable products can be updated.

Revision History
January 13, 2004: Initial release

Thanks for that posting mtupper, and for bringing it to our attention.
Seems it also affects ISA server H323 forwarding, and presumably
gnomemeeting, intel video phone and cuseeme H323 mode.

I reposted it to the Netmeeting newsgroups.

Cheers - Neil.

Thanks Me, Niel and JP... We downloaded the firmware upgrade from
Quintum on Friday night and it seems to have resolved the issue. It
scares the hell out of me though to see how vulnerable VoIP still is
considering the amount of business I had depending on it that was
basically out for 2 days... The same cant be said about a DMS switch
with SS7 - no wonder all the old-shoolers are so reluctant to accept
VoIP.
