CrushFTP: Cross-Site Request Forgery in the web administration interface
Summary
CrushFTP before 7.3.0 contains a Cross-Site Request Forgery vulnerability in its web administration interface. CSRF protection is disabled by default. An attacker can lure a logged-in administrator to a malicious page that sends POST requests to commands such as setUserItem, creating root-access users or changing server configuration.
Affected
- CrushFTP versions 0 to before 7.3.0 (CNA record, default configuration)
Fixed in
- Version 7.3.0 according to the CNA record. The vendor release page does not confirm this wording.
- Unknown whether later 7.x releases contain further fixes for this issue.
Workaround
- No vendor workaround found.
- Restrict access to the web administration interface to a management network or VPN.
Exploitation
- Public proof of concept: yes (Exploit-DB 36126, published 2015).
- Exploited in the wild: no evidence found. Not listed in CISA KEV.
- NVD analysis was still pending at the time of data collection.
Our recommendation
- Upgrade CrushFTP to the latest vendor release, at least 7.3.0.
- Restrict the web administration interface to trusted networks or VPN access.
- Ensure administrators log out before browsing the internet and use separate accounts for admin tasks.
- Review existing administrator and user accounts for unexpected entries, especially root-level accounts.
- Monitor for new or changed users and configuration changes.
