CVE-2026-107639 ILIAS-eLearning e.V. CVE debrief

Who should care

Defenders responsible for ILIAS eLearning platform security, especially those with question author upload capabilities, should assess exposure and prioritize patching or mitigation.

Why it matters

Defenders should prioritize patching or mitigating CVE-2026-107639 due to potential remote code execution risks via argument injection in ILIAS eLearning platform versions before 9.24, 10.12, and 11.5.

• Potential remote code execution
• Question author exploitation via image map question uploads
• Possible write of PHP files under the web root

Technical summary

The ILIAS eLearning platform contains an argument injection vulnerability in the assImagemapQuestionGUI component. This allows question authors to inject ImageMagick convert options via uploaded image filenames, potentially leading to remote code execution. The vulnerability is confirmed in ILIAS versions before 9.24, 10.12, and 11.5. Defenders should prioritize patching or mitigating this vulnerability, especially in environments where question authors have upload capabilities. The vulnerability can be exploited by embedding tab-separated options in uploaded image filenames, which escapeshellcmd() does not neutralise, to write a PHP file under the web root and achieve remote code execution.

Defensive priority

Defenders should prioritize patching or mitigating this vulnerability, especially in environments where question authors have upload capabilities.

Recommended defensive actions

• Patch ILIAS to version 9.24, 10.12, or 11.5
• Restrict question author upload capabilities
• Monitor for suspicious image map question uploads
• 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
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The vulnerability is confirmed in ILIAS versions before 9.24, 10.12, and 11.5. The CVE record and NVD entry provide details on the affected versions and potential impact. Defenders should confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. The vulnerability allows question authors to inject ImageMagick convert options via uploaded image filenames, potentially leading to remote code execution.
