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

Medium Nessus Plugin ID 81882

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.

Solution

Upgrade to Opera version 28.0 or later.
