CVE-2024-38475

一、漏洞信息
 漏洞编号：[CVE-2024-38475](https://nvd.nist.gov/vuln/detail/CVE-2024-38475)
 漏洞归属组件：[httpd](https://gitee.com/src-openeuler/httpd)
 漏洞归属的版本：2.4.43,2.4.46,2.4.48,2.4.51,2.4.55,2.4.58
 CVSS V3.0分值：
  BaseScore：9.1 Critical
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
 漏洞简述：
  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.

二、漏洞分析结构反馈
 影响性分析说明：
  在Apache HTTP Server 2.4.59及更早版本中，mod_rewrite中的输出转义不正确，使得攻击者能够将URL映射到允许由服务器提供服务但任何URL都无法故意/直接访问的文件系统位置，从而导致代码执行或源代码泄漏。服务器上下文中使用反向引用或变量作为替换的第一段的替换会受到影响。一些不安全的RewiteRules将被此更改破坏，并且重写标志“UnsafePrefixStat”可用于在确保替换受到适当限制后选择返回。
