CrushFTP AWS4-HMAC Authentication Bypass

Created
04/04/2025

Description

This module leverages an authentication bypass in CrushFTP 11 < 11.3.1 and 10 < 10.8.4. Attackers with knowledge of a valid username can provide a crafted S3 authentication header to the CrushFTP web API to authenticate as that user without valid credentials. When successfully executed, the exploit will output working session cookies for the target user account.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
