Check Point Patches Critical Zero-Day CVE-2026-93616 Enabling Unauthenticated Remote Code Execution on Management Servers
Check Point has addressed a critical zero-day vulnerability tracked as CVE-2026-93616 with a CVSS score of 9.8 that allowed remote unauthenticated attackers to upload and execute arbitrary scripts on management servers. The flaw combined directory traversal with insecure file handling, enabling attackers to escape the intended directory and place scripts in executable locations. Affected products include Security Management Server, Multi-Domain Security Management Server, Log Server, Multi-Domain Log Server, and SmartEvent. Targeted attacks were observed starting July 23 before public disclosure, though exploitation remained limited. Vulnerable versions span multiple R82, R81, and R80 releases, with fixes now available through specific hotfixes and Jumbo Takes. Administrators are advised to apply patches immediately, place management servers behind a Security Gateway, and restrict TCP port 19009 access. Detection guidance includes reviewing cpm.elg logs for unusually long usernames and ReflectionUtils errors containing directory traversal sequences.
