The remote Blue Coat ProxySG device’s SGOS self-reported version is 6.4 prior to 6.4.6.4. It, therefore, contains a bundled version of OpenSSL that has multiple flaws, including an unspecified error that could allow an attacker to cause usage of weak keying material leading to simplified man-in-the-middle attacks.
