According to its self-reported version, the Tenable Nessus application running on the remote host is 10.x prior to 10.3.2. It is, therefore, affected by multiple vulnerabilities, including:

  • A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking.
    (CVE-2022-3786, CVE-2022-3602)

  • In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations. (CVE-2022-43680)

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