A vulnerability exists in RTU IEC 61850 client and server functionality that could impact the availability if renegotiation of an open IEC61850 TLS connection takes place in specific timing situations, when IEC61850 communication is active.
Precondition is that IEC61850 as client or server are configured using TLS on RTU500 device. It affects the CMU the IEC61850 stack is configured on.
A vulnerability exists in the RTU500 that allows for authenticated and authorized users to bypass secure update,
if secure update feature was not enabled on all CMUs of a RTU500. If a malicious actor successfully exploits this vulnerability, they could use it to update the RTU500 with unsigned firmware.
