Tenable Nessus < 7.1.4 Multiple Vulnerabilities (TNS-2018-17)

Medium Nessus Plugin ID 120198

Synopsis

Tenable Nessus running on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 7.1.4. It is, therefore, affected by multiple vulnerabilities:

- Tenable Nessus contains a flaw in the bundled third-party component OpenSSL library's key handling during a TLS handshake that causes a denial of service vulnerability due to key handling during a TLS handshake. (CVE-2018-0732)

- Tenable Nessus contains a flaw in the bundled third-party component OpenSSL library's DSA signature algorithm that renders it vulnerable to a timing side channel attack.
An attacker could leverage this vulnerability to recover the private key. (CVE-2018-0734)

- Tenable Nessus contains a flaw in the bundled third-party component OpenSSL library's RSA Key generation algorithm that allows a cache timing side channel attack to recover the private key. (CVE-2018-0737)

- Tenable Nessus contains a flaw in the bundled third-party component OpenSSL library's Simultaneous Multithreading (SMT) architectures which render it vulnerable to side-channel leakage. This issue is known as 'PortSmash'. An attacker could possibly use this issue to perform a timing side-channel attack and recover private keys. (CVE-2018-5407)

Solution

Upgrade to Tenable Nessus version 7.1.4 or later.
