A vulnerability exists in the RTU500 web server com- ponent that can cause a denial of service to the RTU500 CMU application if a specially crafted mes- sage sequence is executed on a WebSocket connec- tion. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to ex- ploit this vulnerability.
