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 was found in Cisco Unified Communications Manager up to 5.x (Unified Communication Software) and classified as critical. This issue affects an unknown code block of the file risdc.exe. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the Real-Time Information Server (RIS) Data Collector service (RisDC.exe) in Cisco Unified Communications Manager (CUCM, formerly CallManager) before 20070711 allow remote attackers to execute arbitrary code via crafted packets, resulting in a heap-based buffer overflow.

The bug was discovered 07/11/2007. The weakness was published 07/11/2007 (Website). The advisory is shared at cisco.com. The identification of this vulnerability is CVE-2006-5278 since 10/13/2006. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

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.

Upgrading to version 5.1%281%29 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (19057). Similar entry is available at 37796.
