Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Tomcat是美国阿帕奇（Apache）基金会的一款轻量级Web应用服务器。用于实现对Servlet和JavaServer Page（JSP）的支持。 Apache Tomcat 11.0.0-M1版本至11.0.14版本、10.1.0-M1版本至10.1.49版本、9.0.0-M1版本至9.0.112版本和8.5.0版本至8.5.100版本存在输入验证错误漏洞，该漏洞源于未验证SNI扩展提供的与HTTP主机标头字段提供的主机名是否一致，可能导致绕过客户端证书身份验证。

Vulnerability Title
Apache Tomcat: Client certificate verification bypass due to virtual host mapping
Source: CVE Program / CVE List V5
Vulnerability Description
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.
