Quick assessment
Affected
Apache Software Foundation Apache HTTP Server
Exploitation
Confirmed exploitation in the wild; remediate immediately
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
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 2.4.59及之前版本存在安全漏洞，该漏洞源于输出转义不当，允许攻击者将URL映射无法通过任何URL直接访问的文件系统位置，从而导致代码执行或源代码泄露。

Vulnerability Title
Apache HTTP Server weakness in mod_rewrite when first segment of substitution matches filesystem path.
Source: CVE Program / CVE List V5
Vulnerability Description
Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.
Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained.
