Details

ILIAS versions before 9.23, 10.11, and 11.4 contain an authorization bypass vulnerability in ilObjGroupGUI where saveMapSettingsObject() and updateGroupTypeObject() perform state-changing operations without write permission checks. Authenticated users with only read access to a group can craft POST requests to modify group map settings and didactic template assignments, changing group modes and permissions for all members.

Severity

5.4 (Medium)
