Description
AI Translation Available
A logic vulnerability (fail-open condition) has been identified within the Metasploit Framework's JSON-RPC web service interface. When an exception occurs during the database health check (db.check) and the environment variable MSF_WS_JSON_RPC_API_TOKEN is not explicitly set, the application resets the internal state flag msf.auth_initialized to false. The ApiToken Warden authentication strategy misinterprets this false value as an indicator that authentication is not initialized or required, thereby granting unauthenticated local access to the JSON-RPC request dispatcher.
