Description:
Cody Pierce has reported a vulnerability in Cisco Unified Communications Manager (CUCM), which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the CTL Provider Service (CTLProvider.exe) and can be exploited to cause a heap-based buffer overflow via a specially crafted packet sent to default port 2444/TCP.
Successful exploitation allows execution of arbitrary code.
The vulnerability affects the following versions:
* Cisco Unified CallManager 4.0
* Cisco Unified CallManager 4.1 versions prior to 4.1(3)SR5c
* Cisco Unified Communications Manager 4.2 versions prior to 4.2(3)SR3
* Cisco Unified Communications Manager 4.3 versions prior to 4.3(1)SR1
Solution:
Apply updates.
CUCM 4.0:
Update to a fixed version of CUCM 4.1 or later.
CUCM 4.1:
Update to CUCM 4.1(3)SR5c, CUCM 4.1(3)SR6, or later.
