ProFTPD Auth API Multiple Auth Module Authentication Bypass

medium Nessus Plugin ID 25040
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.


Upgrade to the latest (CVS) version of this software.
