CVE-2024-45614

一、漏洞信息
 漏洞编号：[CVE-2024-45614](https://nvd.nist.gov/vuln/detail/CVE-2024-45614)
 漏洞归属组件：[rubygem-puma](https://gitee.com/src-openeuler/rubygem-puma)
 漏洞归属的版本：3.12.6,4.3.9,5.5.2,5.6.5
 CVSS V3.0分值：
  BaseScore：5.4 Medium
  Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N
 漏洞简述：
  Puma is a Ruby/Rack web server built for parallelism. In affected versions clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users relying on proxy set variables is affected. v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win. Users are advised to upgrade. Nginx has a underscores_in_headers configuration variable to discard these headers at the proxy level as a mitigation. Any users that are implicitly trusting the proxy defined headers for security should immediately cease doing so until upgraded to the fixed versions.
