Account enumeration via unrestricted user search

Published Jun 21, 2022 · Updated Aug 3, 2024

Information disclosure in sr.solutions UserTakeOver before 4.0.1 allows remote authenticated users to enumerate ILIAS accounts. The plugin's search command returns the complete user list to a regular logged-in account when the caller knows the site-specific search URL. The exposure is limited to account identities; no ability to impersonate users, modify data, or interrupt service is reported.
