Serviio Media Server checkStreamUrl Command Execution

Description

This module exploits an unauthenticated remote command execution vulnerability in the console component of Serviio Media Server versions 1.4 to 1.8 on Windows operating systems. The console service (on port 23423 by default) exposes a REST API which which does not require authentication. The 'action' API endpoint does not sufficiently sanitize user-supplied data in the 'VIDEO' parameter of the 'checkStreamUrl' method. This parameter is used in a call to cmd.exe resulting in execution of arbitrary commands. This module has been tested successfully on Serviio Media Server versions 1.4.0, 1.5.0, 1.6.0 and 1.8.0 on Windows 7.

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.
