TITLE

CUCM of CTL Provider Vulnerability in arbitrary code execution in service

DESCRIPTION

Off-by-one error in the Certificate Trust List (CTL) Provider service (CTLProvider.exe) in Cisco Unified Communications Manager (CUCM, formerly CallManager) before 20070711 allow remote attackers to execute arbitrary code via a crafted packet that triggers a heap-based buffer overflow. Cisco Unified Communications Manager is prone to multiple heap-based buffer-overflow vulnerabilities because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. An attacker can exploit these issues to execute arbitrary code within the context of the vulnerable application. Successful exploits may result in a complete compromise of affected servers. Failed exploit attempts will likely result in denial-of-service conditions. A single-byte overflow vulnerability exists in the CTLProvider.exe and RisDC.exe service components of CUCM, which could be exploited by a remote attacker to render the device unusable or take control of the affected system. ---------------------------------------------------------------------- Try a new way to discover vulnerabilities that ALREADY EXIST in your IT infrastructure.

Note: This vulnerability does not affect CUCM 3.x. 2) An integer overflow error in the Real-Time Information Server (RIS) Data Collector service (RisDC.exe) can be exploited to cause a heap-based buffer overflow by sending specially crafted packets to the vulnerable service (default port 2556/TCP). Successful exploitation may allow execution of arbitrary code. SOLUTION: Apply updated versions: Vulnerability #1 is corrected in CUCM versions 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 and 5.1(2). Vulnerability #2 is corrected in CUCM versions 3.3(5)SR2b, 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 and 5.1(2). See vendor advisory for a detailed patch matrix.
