The version of Tomcat installed on the remote host is prior to 9.0.113. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.113_security-9 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. (CVE-2025-66614)

  - Improper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the     GET method. If a security constraint was configured to allow HEAD requests to a URI but deny GET requests,     the user could bypass that constraint on GET requests by sending a (specification invalid) HEAD request     using HTTP/0.9. 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. Older, EOL versions are also affected. Users are recommended to     upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fixes the issue.
    (CVE-2026-24733)

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