The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the K13400 advisory.
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a BEAST attack. (CVE-2011-3389)
The CBC mode in the TLS protocol, as used in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, and other products, allows remote web servers to obtain plaintext data by triggering multiple requests to a third-party HTTPS server and sniffing the network during the resulting HTTPS session, aka TLS Protocol Vulnerability.
(CVE-2012-1870)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
