Cisco Skinny Client Control Protocol Firmware memory corruption

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.

Detailsinfo

A vulnerability was found in Cisco Skinny Client Control Protocol (the affected version is unknown). It has been classified as very critical. This affects an unknown code of the component Firmware. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in Cisco Unified IP Phone 7940, 7940G, 7960, and 7960G running SIP firmware might allow remote SIP servers to execute arbitrary code via a crafted challenge/response message.

The bug was discovered 02/13/2008. The weakness was presented 02/14/2008 (Website). The advisory is shared at cisco.com. This vulnerability is uniquely identified as CVE-2008-0531 since 01/31/2008. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 08/05/2019).

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 $25k-$100k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 43191 (Cisco Unified IP Phone Overflow and Denial of Service Vulnerabilities).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (40498), SecurityFocus (BID 27774†), OSVDB (41562†), Secunia (SA28935†) and SecurityTracker (ID 1019411†). See VDB-41072, VDB-41071, VDB-41070 and VDB-41069 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
