F5 Networks BIG-IP : TMM SSL/TLS virtual server vulnerability (K39508724)

high Nessus Plugin ID 93749

Language:

Synopsis

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

Description

TMM SSL/TLS virtual server using CBC cipher may be vulnerable to a 'Vaudenay timing attack' aka 'Padding oracle attack.'(CVE-2016-6907)

The BIG-IP system may be vulnerable to a padding oracle attack on the following platforms :

The VIPRION B4450 blade and BIG-IP 2000 and 4000 series platforms are vulnerable with any CBC cipher (not AES-GCM or RC4).

BIG-IP Virtual Edition (VE) and cloud (not vCMP) are vulnerable with any CBC cipher (not AES-GCM or RC4).

All other hardware platforms with the Cavium Nitrox card that negotiate the Camellia cipher are vulnerable. Note : The Camellia cipher was introduced in BIG-IP 12.0.0 and is always processed in software.

Note : BIG-IP platforms that use the Cavium Nitrox card can become vulnerable if hardware crypto is disabled, as software crypto will not use the Cavium Nitrox card.For example, a Common Criteria deployment will disable the Cavium Nitrox card and introduce this vulnerability.

Note : All ciphers supported by the BIG-IP system, other than AES-GCM and RC4, are CBC mode ciphers,even if the cipher name does not explicitly containthe word CBC.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K39508724.
