Amlibweb NetOpacs webquery.dll Stack Buffer Overflow

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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
