Name of the Vulnerable Software and Affected Versions
FreeScout versions prior to 1.8.213
Description
Attachment download tokens are generated using a weak and predictable formula:
md5(APP KEY + attachment id + size). Because attachment id is sequential and size can be brute-forced within a small range, an unauthenticated attacker can forge valid tokens to download private attachments without credentials.Recommendations
Update to version 1.8.213.
