CVE-2026-93616: Critical Unauthenticated RCE in Check Point Management Server
In September 2026, Check Point disclosed CVE-2026-93616, a critical unauthenticated remote code execution flaw affecting Security Management Server and Log Server versions R80.30 through R80.40 prior to hotfix CP‑HF‑2026‑09‑15. The vulnerability, scored CVSS v3.1 9.8, stems from insufficient input validation in the web‑based management interface’s file upload endpoint (/msa/upload.php), allowing an attacker to embed directory‑traversal sequences (e.g., \"../\") in the filename parameter, write arbitrary scripts outside the intended directory, and execute them with root privileges. Active exploitation has been observed in targeted attacks against high‑value enterprises, prompting emergency patches via LivePatch and advisories from Check Point, CISA, and multiple threat‑intel feeds.
