Secunia Advisory: SA29831  
Release Date: 2008-04-16

Critical:
Highly critical
Impact: System access
Where: From remote
Solution Status: Unpatched

Software:BigAnt Messenger 2.x
Description:
Matteo Memelli has discovered a vulnerability in BigAnt Messenger, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the AntServer Module (AntServer.exe) and can be exploited to cause a stack-based buffer overflow e.g. by sending a specially crafted, overly long HTTP GET request to default port 6080/TCP.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 2.2. Other versions may also be affected.

Solution:
Restrict network access to the AntServer Module.
