SolarWinds Orion NPM before 12.4 suffers from a SYSTEM remote code execution vulnerability in the OrionModuleEngine service. This service establishes a NetTcpBinding endpoint that allows remote, unauthenticated clients to connect and call publicly exposed methods. The InvokeActionMethod method may be abused by an attacker to execute commands as the SYSTEM user.
