一、漏洞信息
漏洞编号：CVE-2023-32681
漏洞归属组件：python-requests
漏洞归属的版本：2.24.0,2.25.1,2.26.0,2.27.1,2.28.1
CVSS V3.0分值：
BaseScore：6.1 Medium
Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N
漏洞简述：
Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to destination servers when redirected to an HTTPS endpoint. This is a product of how we use rebuild_proxies to reattach the Proxy-Authorization header to requests. For HTTP connections sent through the tunnel, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server. However when sent over HTTPS, the Proxy-Authorization header must be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious actor to potentially exfiltrate sensitive information. This issue has been patched in version 2.31.0.
