A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
