CVE-2026-24138 FOGProject CVE debrief

Who should care

Defenders responsible for FOG installations, particularly those using versions 1.5.10.1754 and below, should assess exposure and potential impact. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify exposure, assess potential impact, and implement compensating controls to limit access to internal resources.

Why it matters

CVE-2026-24138 is an unauthenticated SSRF vulnerability in FOG that can be used to access internal resources. Defenders should prioritize verifying exposure and assessing potential impact.

• Potential access to internal resources
• Possible data leakage or unauthorized access

Technical summary

The vulnerability is caused by an unauthenticated SSRF issue in getversion.php, which can be triggered by providing a user-controlled URL parameter. This issue appears to be reachable without an authenticated web session when the request includes newService=1. The vulnerability can be used to fetch both internal websites and files on the machine running FOG, potentially allowing access to sensitive information or disrupting service. Defenders should prioritize verifying exposure and assessing potential impact, as the vulnerability can be used to access internal resources.

Defensive priority

Recommended defensive actions

• Verify exposure by checking FOG version and configuration
• Assess potential impact by identifying internal resources that could be accessed
• Implement compensating controls to limit access to internal resources
• Review relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
