CVE-2026-93616

Summary

Check Point Multiple Products Path Traversal Vulnerability

Check Point Security Management Server, Multi-Domain Security Management Server, Log Server, Multi-Domain Log Server, and SmartEvent contain a path traversal vulnerability that allows an unauthenticated attacker to upload and execute arbitrary scripts.

Published 2026-09-22 · first seen here 2026-10-10

CISA required action (due 2026-09-25): Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Analysis & write-ups

No technical write-up from a research team yet. Contact Zero checks Unit 42, Google/Mandiant, Microsoft, Talos, CrowdStrike, Rapid7, watchTowr and others several times a day, plus NVD and CISA reference links.

Exploit availability

Public exploit code lowers the bar for attackers, so prioritise patching and hunting. These repositories are unverified. Fake PoCs that contain malware are common, so never run them outside an isolated lab.

Where it shows in your logs

CISA requires forensic triage for this CVE (BOD 26-04): check affected systems for signs of compromise, don't just patch.

Edge or network appliance (firewall, VPN, gateway) · Path traversal (read or write arbitrary files) high confidence

Appliances usually run no EDR, so device logs, firewall flow logs and the vendor's integrity checker are often the only evidence. Get the logs off the box: attackers often wipe local logs.

What to look for

• Requests containing ../, ..%2f, %2e%2e%2f, ..\ or double-encoded variants
• Successful (200) responses to requests for config files, keys or password stores (web.config, /etc/passwd, .env)
• If file write is possible: new files in startup, cron or web folders
• Configuration changes, new local admin accounts or new VPN users on the appliance
• Admin or VPN logins from unfamiliar IPs, especially VPS or hosting providers
• New outbound connections from the appliance's own IP (it should rarely start connections)
• Gaps in the appliance's logs, unexpected reboots or crashes, or logs that were cleared

Data sources

A generic baseline worked out from the product type and weakness (CWE-22), not a detection. Check table and field names against your environment. Hunt queries for Sigma, Splunk, Sentinel and CrowdStrike are coming.
