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.


Check whether it is possible to determine if remote accounts are valid.


In order to avoid false positives, this plugin determines if the remote system accepts any kind of login. Some SSH implementations claim that a login has been accepted when it has not.
