FreeScout has Predictable Attachment Token that Allows Unauthenticated Private File Download via Brute Force
Description d'origine
La description telle que publiée par la source (souvent en anglais).
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, attachment download tokens are generated using a weak and predictable formula: md5(APP_KEY + attachment_id + size). Since attachment_id is sequential and size can be brute-forced in a small range, an unauthenticated attacker can forge valid tokens and download any private attachment without credentials. Version 1.8.213 fixes the issue.
