"According to its self-reported version, the Tenable Nessus Agent running on the remote host is prior to 10.6.4. It is,
therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-09 advisory.

  - Two separate vulnerabilities were discovered, reported and fixed:When installing Nessus Agent to a
    directory outside of the default location on a Windows host, Nessus Agent versions prior to 10.6.4 did not
    enforce secure permissions for sub-directories. This could allow for local privilege escalation if users
    had not secured the directories in the non-default installation location. - CVE-2024-3291A race condition
    vulnerability exists where an authenticated, local attacker on a Windows Nessus Agent host could modify
    installation parameters at installation time, which could lead to the execution of arbitrary code on the
    Nessus host. - CVE-2024-3292 Tenable has released Nessus Agent 10.6.4 to address these issues. The
    installation files can be obtained from the Tenable Downloads Portal
    (https://www.tenable.com/downloads/nessus-agents). (CVE-2024-3291, CVE-2024-3292)

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