Blue Coat ProxySG 6.5.x / 6.2.x / 5.5 OpenSSL Vulnerability (FREAK)
Medium Nessus Plugin ID 82663
SynopsisThe remote device is affected by a security feature bypass vulnerability.
DescriptionThe remote Blue Coat ProxySG device's self-reported SGOS version is 6.5 prior to 126.96.36.199, or version 6.2 prior to 188.8.131.52, or else any version of 5.5. Therefore, it contains a bundled version of OpenSSL 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 version 184.108.40.206 / 220.127.116.11 or later
