CVE-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') •

CVE-2023-28321 – curl: IDN wildcard match may lead to Improper Cerificate Validation
https://notcve.org/view.php?id=CVE-2023-28321
An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`. A flaw was found in the Curl package. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1950627 https://lists.debian.org/debian-lts-announce/2023/10/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4I75RDGX5ULSSCBE5BF3P5I5SFO7ULQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z2LIWHWKOVH24COGGBCVOWDXXIUPKOMK https://security.gentoo • CWE-295: Improper Certificate Validation •
CVE-2023-28322 – curl: more POST-after-PUT confusion
https://notcve.org/view.php?id=CVE-2023-28322
An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST. A use-after-free flaw was found in the Curl package. This issue may lead to unintended information disclosure by the application. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1954658 https://lists.debian.org/debian-lts-announce/2023/12/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4I75RDGX5ULSSCBE5BF3P5I5SFO7ULQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z2LIWHWKOVH24COGGBCVOWDXXIUPKOMK https://security.gentoo • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation •
