神龙判断

是否为 Web 类漏洞： 是

判断理由：

是。这个漏洞涉及Apache Tomcat的AJP Connector，默认配置中监听所有IP地址，这使得攻击者能够利用AJP协议的高信任级别，执行如返回任意文件或以JSP形式处理文件等操作，进而可能实现远程代码执行。此问题需在网络服务端进行修复或配置更改以减少风险。
提示
尽管我们采用了先进的大模型技术，但其输出仍可能包含不准确或过时的信息。
神龙会尽力确保数据准确，但也请结合实际情况进行甄别与判断。
神龙祝您一切顺利！

漏洞描述信息
When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.

漏洞描述信息
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 7.0.100版本之前的7.*版本、8.5.51版本之前的8.*版本和9.0.31版本之前的9.*版本中的Tomcat AJP协议存在安全漏洞。攻击者可利用该漏洞读取或包含Tomcat上所有webapp目录下的任意文件，如 webapp 配置文件或源代码等。
