QFinch assessment
Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, exposes a .NET Remoting service in which an unauthenticated attacker can invoke a method vulnerable to path traversal to read arbitrary files. This vulnerability can be escalated to remote code execution by retrieving the .NET machine keys.
