Live Exploit TrackerCrushFTP - Authentication Bypass (CVE-2025-31161)
CrushFTP versions 10.0.0 through 10.8.3 and 11.0.0 through 11.3.0 are affected by a vulnerability that allows authentication bypass and takeover of the crushadmin account (unless a DMZ proxy instance is used), as exploited in the wild in March and April 2025, aka "Unauthenticated HTTP(S) port access." A race condition exists in the AWS4-HMAC (compatible with S3) authorization method of the HTTP component of the FTP server. The server first verifies the existence of the user by performing a call to login_user_pass() with no password requirement.
