What to do

AI-suggested

1. Immediate mitigation involves updating the MZ Automation LibIEC61850 library to the fixed version that includes commit ac925fae8e281ac6defcd630e9dd756264e9c5bc or later, once available. Monitor official repositories and vendor advisories for patches. 2. Until patches are applied, restrict network access to MMS clients by implementing strict firewall rules and network segmentation to limit exposure to untrusted MMS servers. 3. Employ deep packet inspection and anomaly detection systems to identify and block malformed MMS FileDirResponse messages indicative of exploitation attempts. 4. Conduct thorough code audits and fuzz testing on MMS client implementations to detect similar buffer overflow vulnerabilities proactively. 5. Implement robust intrusion detection and incident response plans tailored for industrial control system environments to quickly identify and respond to exploitation attempts. 6. Engage with vendors and community maintainers to accelerate patch development and share threat intelligence related to this vulnerability. 7. Where possible, deploy application-layer gateways or protocol proxies that validate MMS traffic and enforce strict protocol compliance to mitigate malformed message attacks.

Description

Multiple Buffer overflows in the MMS Client in MZ Automation LibIEC61850 before commit ac925fae8e281ac6defcd630e9dd756264e9c5bc allow a malicious server to cause a stack-based buffer overflow via the MMS FileDirResponse message.
