CVE-2023-3304Public exploitNetwork attack vector

Authenticated message deletion via missing ownership check

Published Jun 23, 2023 · Updated Nov 7, 2024

Improper access control in Admidio before 4.2.9 allows remote authenticated users to delete messages belonging to other users. The messages.php deletion path loads a message by an attacker-supplied msg_uuid and calls delete() without verifying that its sender is the current user. Any signed-in member who obtains another message UUID can permanently remove that message without user interaction.
