What to do

AI-suggested

1. Immediate network segmentation: Isolate devices using the vulnerable MMS Client from untrusted networks and restrict access to trusted management networks only. 2. Deploy strict firewall rules and intrusion detection systems to monitor and block suspicious MMS IdentifyResponse traffic. 3. Conduct thorough inventory and identify all systems using the MZ Automation LibIEC61850 library to assess exposure. 4. Apply any available patches or updates from the library maintainers as soon as they are released. 5. If patches are not yet available, consider temporary mitigations such as disabling MMS Client functionality or replacing the library with alternative implementations where feasible. 6. Implement strict input validation and anomaly detection at the network level to detect malformed MMS messages. 7. Regularly audit and monitor logs for unusual activity related to MMS communications. 8. Engage with vendors and industrial control system integrators to ensure awareness and coordinated response. 9. Develop and test incident response plans specific to industrial control system compromises involving IEC 61850 protocols.

Description

Multiple Buffer overflows in the MMS Client in MZ Automation LibIEC61850 before commit 1f52be9ddeae00e69cd43e4cac3cb4f0c880c4f0 allow a malicious server to cause a stack-based buffer overflow via the MMS IdentifyResponse message.
