Submit #897723: Admidio <= 5.1.0 Authentication Bypass Issuesinfo

TitelAdmidio <= 5.1.0 Authentication Bypass Issues
BeschreibungAn authentication bypass vulnerability was found in the "/modules/forum.php" file of Admidio. The module visibility system supports three modes: 0 (disabled), 1 (public), and 2 (login-only). When an administrator sets the forum module to "login-only" mode (forum_module_enabled = 2), the application fails to enforce the authentication check. The if-elseif chain at lines 54-59 only handles mode 0 and mode 1, but entirely omits the condition for mode 2. As a result, code execution falls through to the switch statement, and all read operations (cards, list, topic) are served to unauthenticated users without any access control check.
