sipXtapi INVITE Message CSeq Field Header Remote Overflow

This script is Copyright (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote host contains an application that is vulnerable to a remote
buffer overflow attack.

Description :

The remote host is running a SIP user agent that appears to be compiled
using a version of SIP Foundry's SipXtapi library before March 24, 2006.
Such versions contain a buffer overflow flaw that is triggered when
processing a specially crafted packet with a long value for the 'CSeq'
field. A remote attacker may be able to exploit this issue to execute
arbitrary code on the affected host subject to the privileges of the
current user.
