Description

This module exploits a stack buffer overflow in Amlib's Amlibweb
Library Management System (NetOpacs). The webquery.dll
API is available through IIS requests. By specifying
an overly long string to the 'app' parameter, SeH can be
reliably overwritten allowing for arbitrary remote code execution.
In addition, it is possible to overwrite EIP by specifying
an arbitrary parameter name with an '=' terminator.
