BlackBerry <= 7.1 and 10.x < 10.3.1.1779 SSL/TLS EXPORT_RSA Ciphers Downgrade MitM (KB36811) (FREAK)
Medium Nessus Plugin ID 82296
SynopsisThe version of BlackBerry OS is affected by the FREAK vulnerability.
DescriptionAccording to its version number, the BlackBerry OS installed on the mobile device is the BlackBerry OS equal or prior to version 7.1, or else it is the BlackBerry 10 OS prior to version 10.3.1.1779. 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.
SolutionUpgrade to BlackBerry 10.3.1.1779 or later.
