漏洞描述
中文描述:

Apache HTTP Server是美国阿帕奇（Apache）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存在代码问题漏洞，该漏洞是由于系统对用户的输入没有进行严格的过滤导致，攻击者可以构造恶意数据对目标服务器进行SSRF攻击。该漏洞可做为攻击目标服务器内网的跳板，以此对服务器所在内网进行端口扫描、攻击运行在内网的应用程序、下载内网资源等。

英文描述:

A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
