"According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 10.5.6. It
is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-36 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 10.5.6 updates OpenSSL to version 3.0.12
    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 10.5.6 to address these issues. The installation files can only be obtained via the Nessus
    Feed. (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.");
