+Furthermore, **URLSNDS payload has been introduced** to actively **detect Java deserialization without any vulnerable libraris**. If the plugin find only the URLDNS issue (and no vulnerable libraries), the attacker probably can execute DoS attacks but to achieve Remote Code Execution it is necessary more effort.
