F5 Networks BIG-IP : OpenSSL vulnerability (K23196136) (DROWN)

medium Nessus Plugin ID 100180
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 is different from CVSS.

VPR Score: 4.4

Synopsis

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

Description

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a 'DROWN' attack. (CVE-2016-0800)

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K23196136.
