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.

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

The version of tomcat installed on the remote host is prior to 9.0.115-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT9-2026-024 advisory.

    mproper 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.

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)

    A flaw was found in Tomcat. An improper input validation vulnerability allows an attacker to bypass     security constraints. Specifically, if a security constraint is configured to permit HEAD requests to a     URI but deny GET requests, a malformed or specification invalid HEAD request using the HTTP/0.9 protocol     can bypass the intended denial rule, enabling an attacker to access resources that should be protected.
    (CVE-2026-24733)

    Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat.

    When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not     complete verification or freshness checks on the OCSP response which could allow certificate revocation to     be bypassed.

    This issue affects Apache Tomcat Native:  from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache     Tomcat: from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114.

    The following versions were EOL at the time the CVE was created but areknown to be affected: from 1.1.23     through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected.

    Apache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which     fix the issue.

    Apache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115     or later which fix the issue. (CVE-2026-24734)

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

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

The version of Apache Tomcat installed on the remote host is 9.0.0-M1 prior to 9.0.113, 10.1.0-M1 prior to 10.1.50 or 11.0.0-M1 prior to 11.0.15. It is, therefore, affected by multiple vulnerabilities :

 - 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. (CVE-2026-24733)

 - 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. (CVE-2025-66614)

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tomcat installed on the remote host is prior to 11.0.15. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_11.0.15_security-11 advisory.

  - 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.

The version of Tomcat installed on the remote host is prior to 10.1.50. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_10.1.50_security-10 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)
