Name of the Vulnerable Software and Affected Versions Easergy P3 versions prior to V30.205

Description A buffer copy without checking the size of input vulnerability exists, potentially leading to a buffer overflow, causing program crashes and arbitrary code execution when specially crafted packets are sent to the device over the network. Protection functions and tripping functions via GOOSE can be impacted.

Recommendations For versions prior to V30.205, update to version V30.205 or later to resolve the issue. As a temporary workaround, consider restricting access to the device over the network to minimize the risk of exploitation. Avoid using the GOOSE protocol until the issue is resolved.
