Wing FTP Server SFTP Connection Unspecified DoS

medium Nessus Plugin ID 53373
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.


The remote FTP service is vulnerable to a denial of service attack.


The remote FTP server is running a version of Wing FTP Server earlier than 3.8.0. Such versions reportedly are affected by a denial of service vulnerability that can be triggered when handling SFTP connections.

A remote, unauthenticated attacker may be able to leverage this issue to crash the service and deny access to legitimate users.


Upgrade to version 3.8.0 or later.
