F5 Networks BIG-IP : CRIME vulnerability via TLS 1.2 protocol (K14054)

low Nessus Plugin ID 78139

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data. This allows man-in-the-middle attackers to obtain plain text HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potentially matches an unknown string in an HTTP header, also referred to as a CRIME attack. (CVE-2012-4929)

Impact

Connections to the BIG-IP Configuration utility are at risk.

Note: BIG-IP SSL profiles are not affected.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K14054.
