high Nessus Network Monitor Plugin ID 701238
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 host is running a web browser that is vulnerable to a critical issue within the Network Security Services (NSS) library.


Versions of Mozilla Firefox ESR prior to version 24.8.1 utilize a vulnerable version of the Network Security Services library for cryptographic functionality. The issue occurs from incorrectly check on signature padding, leading to potential signature forgery that can be leveraged for man-in-the-middle attacks over SSL.


Upgrade to Firefox ESR version 24.8.1, or later.
