CVE-2023-36486

Name of the Vulnerable Software and Affected Versions ILIAS versions prior to 7.23 ILIAS versions 8 prior to 8.3

Description The issue is related to the incorrect implementation of the sequence of actions in the ILIAS learning management system. It allows a remote attacker to execute arbitrary system commands on the application server by uploading a workflow definition file with a malicious filename. This can be done by remote authenticated users.

Recommendations For ILIAS versions prior to 7.23, update to version 7.23 or later to resolve the issue. For ILIAS versions 8 prior to 8.3, update to version 8.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the workflow-engine feature until a patch is available. Avoid uploading workflow definition files from untrusted sources to minimize the risk of exploitation.
