CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-32681 – Unintended leak of Proxy-Authorization header in requests
https://notcve.org/view.php?id=CVE-2023-32681
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. • https://github.com/hardikmodha/POC-CVE-2023-32681 https://github.com/psf/requests/commit/74ea7cf7a6a27a4eeb2ae24e162bcc942a6706d5 https://github.com/psf/requests/releases/tag/v2.31.0 https://github.com/psf/requests/security/advisories/GHSA-j8r2-6x86-q33q https://lists.debian.org/debian-lts-announce/2023/06/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/AW7HNFGYP44RT3DUDQXG2QT3OEV2PJ7Y https://lists.fedoraproject.org/archives/list/package-announce@lists.fedorap • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •
CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 2CVE-2018-18074 – python-requests: Redirect from HTTPS to HTTP does not remove Authorization header
https://notcve.org/view.php?id=CVE-2018-18074
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network. El paquete Requests antes de la versión 2.20.0 para Python envía una cabecera de autorización HTTP a un URI http al recibir una redirección same-hostname https-to-http, lo que facilita que los atacantes remotos descibran las credenciales esnifando la red. A credentials-exposure flaw was found in python-requests, where if a request with authentication is redirected (302) from an HTTPS endpoint to an HTTP endpoint on the same host, the Authorization header is not stripped and the credentials can be read in plain text. A man-in-the-middle attacker could exploit this flaw to obtain a user's valid credentials. • http://docs.python-requests.org/en/master/community/updates/#release-and-version-history http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00024.html https://access.redhat.com/errata/RHSA-2019:2035 https://bugs.debian.org/910766 https://github.com/requests/requests/commit/c45d7c49ea75133e52ab22a8e9e13173938e36ff https://github.com/requests/requests/issues/4716 https://github.com/requests/requests/pull/4718 https://usn.ubuntu.com/3790-1 https://usn.ubuntu.com/3790-2 https:/& • CWE-522: Insufficiently Protected Credentials •
