Official Description
Buffer overflow in the archive decompression library (vrAZMain.dll 5.8.22.137), as used in HAURI anti-virus products including (1) ViRobot Expert 4.0, (2) ViRobot Advanced Server, and (3) HAURI LiveCall, allows user-assisted attackers to execute arbitrary code via an ALZ archive containing a file with a long filename.
Technical Analysis
CVE-2005-4786 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
