This Metasploit module exploits a stack based buffer overflow in Ericom AccessNow Server. The vulnerability is due to an insecure usage of vsprintf with user controlled data, which can be triggered with a malformed HTTP request. This Metasploit module has been tested successfully with Ericom AccessNow Server 2.4.0.2 on Windows XP SP3 and Windows 2003 Server SP2.
