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.

VPR Score: 4.4


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


According to its self-reported version, the Tenable Nessus application running on the remote host is 8.x prior to 8.1.1. It is, therefore, affected by multiple vulnerabilities:

- 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 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)


Upgrade to Tenable Nessus version 8.1.1 or later.
