CVE-2024-37891

一、漏洞信息
漏洞编号：CVE-2024-37891
漏洞归属组件：python-pip
漏洞归属的版本：20.2.2,20.3.3,21.3.1,22.3.1,23.1.2,23.3.1
CVSS V3.0分值：
BaseScore：4.4 Medium
Vector：CVSS：3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N
漏洞简述：
urllib3 is a user-friendly HTTP client library for Python. When using urllib3 s proxy support with ProxyManager, the Proxy-Authorization header is only sent to the configured proxy, as expected. However, when sending HTTP requests without using urllib3 s proxy support, it s possible to accidentally configure the Proxy-Authorization header even though it won t have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn t treat the Proxy-Authorization HTTP header as one carrying authentication material and thus doesn t strip the header on cross-origin redirects. Because this is a highly unlikely scenario, we believe the severity of this vulnerability is low for almost all users. Out of an abundance of caution urllib3 will automatically strip the Proxy-Authorization header during cross-origin redirects to avoid the small chance that users are doing this on accident. Users should use urllib3 s proxy support or disable automatic redirects to achieve safe processing of the Proxy-Authorization header, but we still decided to strip the header by default in order to further protect users who aren t using the correct approach. We believe the number of usages affected by this advisory is low. It requires all of the following to be true to be exploited: 1. Setting the Proxy-Authorization header without using urllib3 s built-in proxy support. 2. Not disabling HTTP redirects. 3. Either not using an HTTPS origin server or for the proxy or target origin to redirect to a malicious origin. Users are advised to update to either version 1.26.19 or version 2.2.2. Users unable to upgrade may use the Proxy-Authorization header with urllib3 s ProxyManager, disable HTTP redirects using redirects=False when sending requests, or not user the Proxy-Authorization header as mitigations.

二、漏洞分析结构反馈
影响性分析说明：
当将urllib3的代理支持与ProxyManager一起使用时，Proxy-Authorization标头只会发送到配置的代理，正如预期的。但是，当发送HTTP请求而不使用urllib3的代理支持时，可能会意外配置Proxy-Authorization标头，即使它不会有任何效果，因为请求没有使用转发代理或隧道代理。在这些情况下，urllib3不会将Proxy-Authorization HTTP标头视为携带身份验证材料的标头，因此不会在跨域重定向时剥离该标头;
