RTSP: Invalid Dynamic Port Number
This protocol anomaly triggers when it detects an RTSP transport request to open a new connection on a port number smaller than 1024. This is not supported by the specifications of RTSP and can indicate an attacker trying to create a back-door to a low-port service.
Extended Description
Such conditions could indicate a configuration or implementation error, or it could indicate that an attack to open a backdoor to a lower port is underway.
