Firefox < 41.0.2 'fetch' API Cross-Origin Bypass (Mac OS X)

medium Nessus Plugin ID 86417
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.

Synopsis

The remote Mac OS X host contains a web browser that is affected by a cross-origin restriction bypass vulnerability.

Description

The version of Firefox installed on the remote Mac OS X host is prior to 41.0.2. It is, therefore, affected by a cross-origin restriction bypass vulnerability in the fetch() API due to an incorrect implementation of the Cross-Origin Resource Sharing (CORS) specification. A remote attacker can exploit this, via a malicious website, to access private data from other origins.

Solution

Upgrade to Firefox 41.0.2 or later.
