The remote Wu-FTPd server seems to be vulnerable to a remote flaw. This version contains a flaw that may allow a malicious user to overwrite arbitrary files. The issue is triggered when an attacker sends a specially formatted rnfr command. This flaw will allow a remote attacker to overwrite any file on the system. *** OVS solely relied on the banner of the remote server *** to issue this warning, so it may be a false positive.

Upgrade to Wu-FTPd 2.4.2 or newer
