F5 Networks BIG-IP : TMM TLS virtual server vulnerability (K10065173) (POODLE)

Medium Nessus Plugin ID 122432

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

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

Description

A BIG-IP virtual server configured with a Client SSL profile may be vulnerable to a chosen ciphertext attack against CBC ciphers. When exploited, this may result in plaintext recovery of encrypted messages through a man-in-the-middle (MITM) attack, despite the attacker not having gained access to the server's private key itself.
(CVE-2019-6593 also known as Zombie POODLE and GOLDENDOODLE)

Impact

Exploiting this vulnerability to perform plaintext recovery of encrypted data may reveal session authentication cookies similar to CVE-2014-3566 (POODLE). Only TLS sessions established using CBC mode encryption are vulnerable to this attack.

To exploit this vulnerability, the attacker must have a privileged network position to intercept controlled HTTPS requests, which are generally initiated via JavaScript originating in any browser context.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K10065173.
