ProFTPD Auth API Multiple Auth Module Authentication Bypass

Medium Nessus Plugin ID 25040


It is possible to bypass the authentication scheme of the remote FTP server.


The remote host is running ProFTPd. Due to a bug in the way the remote server is configured and the way it processes the USER and PASS commands, it is possible to log into the remote system by supplying invalid credentials.
