Title
Apache Tomcat存在httpoxy远程代理感染漏洞
Description
Apache Tomcat是美国阿帕奇（Apache）软件基金会下属的Jakarta项目的一款轻量级Web应用服务器，它主要用于开发和调试JSP程序，适用于中小型系统。 httpoxy是一组影响应用程序代码在CGI环境运行的漏洞。该漏洞主要存在于多个Web服务器、Web框架和编程语言中。可对HTTP头部的Proxy字段名变换为“HTTP_PROXY”，Value值不变，进而传递给对应的CGI执行；若CGI或脚本中使用对外请求的组件依赖的是“HTTP_PROXY”环境变量，就可能被污染。未经身份验证的远程攻击者利用漏洞可发起中间人攻击，或在服务器上启动任意主机的连接。 Apache Tomcat存在httpoxy远程代理感染漏洞，该漏洞源于程序未能解决RFC 3875模式下的命名空间冲突。程序未能正确处理来自HTTP_PROXY环境变量中不可信客户端数据应用程序。允许远程攻击者通过精心设计的HTTP请求代理头重定向应用程序的出站HTTP流量到任意一个代理服务器。
