Description

This 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 module has been tested
successfully with Ericom AccessNow Server 2.4.0.2 on Windows XP SP3 and Windows 2003
Server SP2.
