Description
This Metasploit module exploits an Unauthenticated Remote Code Execution (RCE) vulnerability in OpenBullet2.
Attackers can leverage the plain C# execution mode, which lacks reference filtering or API restrictions, to access the file system, spawn processes, and invoke arbitrary .NET APIs as the process user.
The affected versions include releases from 0.2.5.
