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 thus reportedly contains an SFTP bug in which directory creation and logging SFTP commands could lead to an application crash.


Upgrade to Serv-U version or later.
