Firefox < 44.0.2 Service Workers Security Bypass (Mac OS X)

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote Mac OS X host contains a web browser that is affected by
a security bypass vulnerability.

Description :

The version of Mozilla Firefox installed on the remote Mac OS X host
is prior to 44.0.2. It is, therefore, affected by a security bypass
vulnerability due to improper restriction of interaction between
service workers and plugins. An unauthenticated, remote attacker can
exploit this, via a crafted web site that triggers spoofed responses
to requests that use NPAPI, to bypass the same-origin policy.
