"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-014281 advisory.

    Improper Input Validation vulnerability.

    This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from
    9.0.0-M1 through 9.0.112.

    The following versions were EOL at the time the CVE was created but are
    known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected.
    Tomcat did not validate that the host name provided via the SNI
    extension was the same as the host name provided in the HTTP host header
    field. If Tomcat was configured with more than one virtual host and the
    TLS configuration for one of those hosts did not require client
    certificate authentication but another one did, it was possible for a
    client to bypass the client certificate authentication by sending
    different host names in the SNI extension and the HTTP host header field.



    The vulnerability only applies if client certificate authentication is
    only enforced at the Connector. It does not apply if client certificate
    authentication is enforced at the web application.


    Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which
    fix the issue.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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