high Nessus Plugin ID 184164

Language:

Synopsis

An instance of Nessus installed on the remote system is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 10.6.2. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-37 advisory.

 - Nessus leverages third-party software to help provide underlying functionality. Several of the third-party components (OpenSSL, zlib) were found to contain vulnerabilities, and updated versions have been made available by the providers.Out of caution and in line with best practice, Tenable has opted to upgrade these components to address the potential impact of the issues. Nessus 10.6.2 updates OpenSSL to version 3.0.12, and zlib fixes have been applied to address the identified vulnerabilities.Additionally, one other vulnerability was discovered, reported and fixed:Under certain conditions, a low privileged attacker could load a specially crafted file during installation or upgrade to escalate privileges on Windows and Linux hosts. - CVE-2023-5847 Tenable has released Nessus 10.6.2 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus).
 (CVE-2023-45853, CVE-2023-4807, CVE-2023-5847)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Tenable Nessus 10.6.2 or later.
