F5 Networks BIG-IP : SSL acceleration card timing vulnerability (K15500)

medium Nessus Plugin ID 78190

Language:

Synopsis

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

Description

SSL virtual servers in F5 BIG-IP systems 10.x before 10.2.4 HF9, 11.x before 11.2.1 HF12, 11.3.0 before HF10, 11.4.0 before HF8, 11.4.1 before HF5, 11.5.0 before HF5, and 11.5.1 before HF5, when used with third-party Secure Sockets Layer (SSL) accelerator cards, might allow remote attackers to have unspecified impact via a timing side-channel attack. (CVE-2014-4024)

Impact

Under very specific conditions, BIG-IP devices with third-partySecure Sockets Layer (SSL) accelerator cards may be vulnerable to SSL/TLS side channel timing vulnerability attacks. Since this attack requires very accurate timing to succeed, the attack may only be possible if attempted on the same local-area network as the BIG-IP devices.

Note : BIG-IP FIPS devices are not vulnerable.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K15500.
