CVE-2026-110669 cemtan CVE debrief

Who should care

Defenders responsible for cemtan sar2html deployments should assess exposure to remote attacks and verify inventory for affected versions. They should also review compensating controls for exposed systems and track exceptions and retest remediated assets. Security teams and vulnerability management teams should prioritize verifying the presence of affected versions in their inventory and assessing exposure to remote attacks due to missing authentication in

Why it matters

Defenders should prioritize verifying the presence of affected versions in their inventory and assessing exposure to remote attacks due to missing authentication in cemtan sar2html 4.0.0.

• Verify authentication controls for deleteHost, deleteRange, and deleteAll functions
• Assess exposure to remote attacks on affected versions
• Implement compensating controls for authentication

Technical summary

The vulnerability affects the functions deleteHost, deleteRange, and deleteAll in the file sar2html.py of cemtan sar2html 4.0.0, leading to missing authentication. This allows remote attackers to potentially delete data without proper authorization, leading to data loss and system compromise.

Recommended defensive actions

• Verify the presence of affected versions in inventory
• Assess exposure to remote attacks
• Implement compensating controls for authentication
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check 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
