Wing FTP Server SSH Public Key Authentication Bypass
Medium Nessus Plugin ID 55652
SynopsisThe remote FTP service is vulnerable to an authentication bypass attack.
DescriptionThe remote FTP server is running a version of Wing FTP Server earlier than 3.8.8. As such, it is reportedly affected by an authentication bypass vulnerability when SSH public key authentication is used.
An attacker can exploit this issue by logging into the FTP server with a password even though the server is configured to use only public key authentication. Successful exploitation of this issue requires knowledge of valid account credentials.
Note that public key authentication configuration in Wing FTP is set on a per-user basis and that Nessus has not verified that this configuration is in effect for any users.
SolutionUpgrade to version 3.8.8 or later.
