Tenable Nessus Agent < 8.2.4 Multiple Vulnerabilities (TNS-2021-08)

high Nessus Plugin ID 148392

Language:

Synopsis

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

Description

According to its self-reported version, the Tenable Nessus agent running on the remote host is prior to 8.2.4. It is, therefore, affected by multiple vulnerabilities. Nessus Agent leverages third-party software to help provide underlying functionality. Two separate third-party components (OpenSSL and sqlite) were found to contain vulnerabilities, and updated versions have been made available by the providers.

Out of caution and in line with good practice, Tenable opted to upgrade the bundled libraries to address the potential impact of these issues. Nessus Agent 8.2.4 will update OpenSSL to version 1.1.1k and sqlite to version 3.34.1 to address the identified vulnerabilities.

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

Solution

Upgrade to Tenable Nessus Agent version 8.2.4 or later.
