CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, was found in Cisco IOS (Router Operating System). This affects some unknown processing. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

Cisco IOS 12.2 and 12.4, when NAT Skinny Call Control Protocol (SCCP) Fragmentation Support is enabled, allows remote attackers to cause a denial of service (device reload) via segmented SCCP messages, aka CSCsg22426, a different vulnerability than CVE-2008-3811.

The bug was discovered 09/24/2008. The weakness was released 09/26/2008 (Website). It is possible to read the advisory at vupen.com. This vulnerability is uniquely identified as CVE-2008-3810 since 08/27/2008. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 49024 (Cisco IOS NAT Skinny Call Control Protocol Vulnerability), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CISCO and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 43148 (Cisco IOS NAT Skinny Call Control Protocol (cisco-sa-20080924-sccp)).

Applying a patch is able to eliminate this problem. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 5129.
