AI-suggested

European organizations should immediately verify their Zoom Node MMR versions and upgrade to version 5.2.1716.0 or later once available. If you cannot patch yet, network segmentation should be enforced to isolate MMR devices from untrusted networks and restrict meeting participant network access to these devices. Implement strict access controls and monitor network traffic for unusual command execution patterns or anomalies related to MMR devices. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting command injection attempts. Conduct regular audits of Zoom Node MMR configurations and logs to detect potential exploitation attempts. Additionally, organizations should engage with Zoom support for any interim mitigation guidance and monitor threat intelligence feeds for emerging exploit information. Training IT staff on this specific vulnerability and response procedures will enhance readiness.

Description

A Command Injection vulnerability in Zoom Node Multimedia Routers (MMRs) before version 5.2.1716.0 may allow a meeting participant to conduct remote code execution of the MMR via network access.
