Apache HTTP Server是美国阿帕奇（Apache）软件基金会的一款开源网页服务器。该服务器具有快速、可靠且可通过简单的API进行扩充的特点。 Apache HTTP Server 2.4.23及之前的版本中存在安全漏洞，该漏洞源于程序没有解决RFC 3875模式下的命名空间冲突。程序没有正确处理来自HTTP_PROXY环境变量中不可信客户端数据应用程序。远程攻击者借助HTTP请求中特制的Proxy header消息利用该漏洞实施中间人攻击，指引服务器发送连接到任意主机。

Source: CVE Program / CVE List V5
Vulnerability Description
The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.
