CVE-2023-41081— Apache Tomcat Connectors: Unexpected use of first declared worker in mod_jk for unmapped request

Apache Tomcat Connectors: Unexpected use of first declared worker in mod_jk for unmapped request

Important: Authentication Bypass CVE-2023-41081 The mod_jk component of Apache Tomcat Connectors in some circumstances, such as when a configuration included "JkOptions +ForwardDirectories" but the configuration did not provide explicit mounts for all possible proxied requests, mod_jk would use an implicit mapping and map the request to the first defined worker. Such an implicit mapping could result in the unintended exposure of the status worker and/or bypass security constraints configured in httpd. As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. Only mod_jk is affected by this issue. The ISAPI redirector is not affected. This issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48. Users are recommended to upgrade to version 1.2.49, which fixes the issue.

Apache Tomcat 安全漏洞

Apache Tomcat是美国阿帕奇（Apache）基金会的一款轻量级Web应用服务器。该程序实现了对Servlet和JavaServer Page（JSP）的支持。 Apache Tomcat 存在安全漏洞，该漏洞源于当配置中包含了 JkOptions+ForwardDirectories ，但配置没有为所有可能的代理请求提供明确的映射时，mod_jk 会使用隐式映射，这样的隐式映射可能会导致不经意地暴露状态工作进程（status worker），或者绕过在 httpd 中配置的安全约束。
