CVE-2024-33528Public exploitNetwork attack vector

Stored script execution via unvalidated imported object titles

Published May 21, 2024 · Updated Feb 13, 2025

Stored XSS in ILIAS 7 before 7.30 and ILIAS 8 before 8.11 allows remote authenticated users with tutor privileges to execute script via XML import. Object import accepts script-bearing content in a Title XML element, and the course interface renders the stored object title without output encoding. The payload runs whenever a course user views the object, allowing requests in the victim's ILIAS session; reaching administrative functions requires an administrator to visit the course.
