Admidio is an open-source user management solution. Prior to version 5.0.10, the sensitive `mode=export` action in `modules/sso/keys.php` exports a PKCS#12 bundle containing the configured private key and certificate, but the CSRF validation line is commented out. A forged cross-site POST from an administrator session can therefore trigger private key export without a valid form token.
Version 5.0.10 contains a fix.
