high Nessus Plugin ID 152161
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.


A PDF viewer installed on the remote Windows host is affected by multiple vulnerabilities


According to its version, the Foxit Reader application installed on the remote Windows host is prior to 11.0.1. It is, therefore affected by multiple arbitrary code execution vulnerabilities due to a use-after-free flaw in the JavaScript engine. An authenticated, local attacker can exploit this by persuading a victim to open a specially-crafted PDF file, to execute arbitrary code on the system.

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


Upgrade to Foxit Reader version 11.0.1 or later
