CVE-2024-1135

一、漏洞信息
 漏洞编号：[CVE-2024-1135](https://nvd.nist.gov/vuln/detail/CVE-2024-1135)
 漏洞归属组件：[python-gunicorn](https://gitee.com/src-openeuler/python-gunicorn)
 漏洞归属的版本：20.0.4,20.1.0,21.2.0,22.0.0,23.0.0
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
 漏洞简述：
  Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS) vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn s handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure.

二、漏洞分析结构反馈
 影响性分析说明：
                            Gunicorn 未能正确验证 Transfer-Encoding 标头，导致 HTTP 请求走私 (HRS) 漏洞。攻击者可以通过创建包含冲突的 Transfer-Encoding 标头的请求，绕过安全限制并访问受限制的端点。此问题源于 Gunicorn 对 Transfer-Encoding 标头的处理方式，它错误地处理了包含多个冲突的 Transfer-Encoding 标头的请求，无论最终指定的编码是什么，都会将其视为分块请求。此漏洞已被证实允许访问受 gunicorn 限制的端点。此问题已在 22.0.0 版本中得到解决。受影响的用户必须拥有未过滤无效请求的网络路径。如果这些用户无法更新，建议他们通过防火墙或其他机制阻止访问受限端点。
