Opera < 28.0.1750.40 SSL/TLS EXPORT_RSA Ciphers Downgrade MitM (Mac OS X) (FREAK)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.

Synopsis :

The remote Mac OS X host has a web browser installed that is affected
by the FREAK vulnerability.

Description :

The remote Mac OS X host has a version of the Opera web browser
installed that is prior to 28.0.1750.40. It is, therefore, affected by
a security feature bypass vulnerability, known as FREAK (Factoring
attack on RSA-EXPORT Keys), due to the support of weak EXPORT_RSA
cipher suites with keys less than or equal to 512 bits. A
man-in-the-middle attacker may be able to downgrade the SSL/TLS
connection to use EXPORT_RSA cipher suites which can be factored in a
short amount of time, allowing the attacker to intercept and decrypt
the traffic.
