Official description
Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, does not correctly verify the name of an attacker-controlled WSDL service, leading to insecure reflection. This can result in remote code execution through either invocation of arbitrary methods or deserialization of untrusted types.
