Detailsinfo

A vulnerability was found in Cisco IP Phone 7940 (IP Phone Software) and classified as critical. This issue affects an unknown code of the component SIP Handler. The manipulation with the input value INVITE leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. The summary by CVE is:

Cisco IP Phone 7940 with firmware P0S3-08-7-00 allows remote attackers to cause a denial of service ("486 Busy" responses or device reboot) via a sequence of SIP INVITE transactions in which the Request-URI lacks a user name, a different vulnerability than CVE-2007-4459.

The weakness was disclosed 12/06/2007 by Olivier with INRIA Lorraine (Website). The advisory is shared at lists.grok.org.uk. The identification of this vulnerability is CVE-2007-5583 since 10/19/2007. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed by MADYNES and been published before and not just after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at lists.grok.org.uk.

The vulnerability is also documented in the databases at X-Force (38853), Exploit-DB (4692), SecurityFocus (BID 26711†), OSVDB (40189†) and Secunia (SA27898†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
