CVE-2007-2165

The Auth API in ProFTPD before 20070417, when multiple simultaneous
authentication modules are configured, does not require that the module
that checks authentication is the same as the module that retrieves
authentication data, which might allow remote attackers to bypass
authentication, as demonstrated by use of SQLAuthTypes Plaintext in
mod_sql, with data retrieved from /etc/passwd.
