According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 10.5.4. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-27 advisory.

  • Nessus leverages third-party software to help provide underlying functionality. One of the third-party components (OpenSSL) was found to contain vulnerabilities, and updated versions have been made available by the provider. 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 10.5.4 updates OpenSSL to version 3.0.10 to address the identified vulnerabilities. Tenable has released Nessus 10.5.4 to address these issues.
    The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus). (CVE-2023-3446, CVE-2023-3817)

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