According to its self-reported version, the Tenable Nessus Agent running on the remote host is prior to 10.7.2 and earlier. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-14 advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.

"According to its self-reported version, the Tenable Nessus Agent running on the remote host is prior to 10.7.2 and
earlier. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-14 advisory.
- Nessus Agent leverages third-party software to help provide underlying functionality. Several of the
third-party components (OpenSSL, expat) 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 Agent Version 10.7.3
updates OpenSSL to version 3.0.15 and expat to version 2.6.3 to address the identified
vulnerabilities. Tenable has released Nessus Agent 10.7.3 to address these issues. The installation files
can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus-agents).
