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 server is affected by a denial of service vulnerability.


The installed version of Serv-U 7.x is earlier than, and is therefore affected by a denial of service vulnerability. By using a specially crafted command such as XCRC, STOU, DSIZ, AVBL, RNTO, or RMDA, it may be possible for an authenticated attacker to render the FTP server temporarily unresponsive.


Upgrade to Serv-U version or later.
