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.


An application running on a remote web server host is affected by a remote code execution vulnerability


The version of Liferay Portal installed on the remote host is affected by a remote code execution vulnerability in its JSON web services component. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to Liferay Portal 6.2.5, 7.0.6, 7.1.3, 7.2.1 or later.
