CVSS: 9.8EPSS: 0%CPEs: 4EXPL: 0CVE-2018-20060 – python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure
https://notcve.org/view.php?id=CVE-2018-20060
urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext. urllib3 en versiones anteriores a la 1.23 no elimina la cabecera HTTP Authorization al seguir una redirección cross-origin (i.e., una redirección que difiere en host, puerto o esquema). Esto puede permitir que las credenciales de la cabecera Authorization se expongan a hosts no planeados o se transmitan en texto claro. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html https://access.redhat.com/errata/RHSA-2019:2272 https://bugzilla.redhat.com/show_bug.cgi?id=1649153 https://github.com/urllib3/urllib3/blob/master/CHANGES.rst https://github.com/urllib3/urllib3/issues/1316 https://github.com/urllib3/urllib3/pull/1346 https://lists.debian.org/debian-lts-announce/2021/06/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5SJERZ • CWE-522: Insufficiently Protected Credentials •

Versions 1.17 and 1.18 of the Python urllib3 library suffer from a vulnerability that can cause them, in certain configurations, to not correctly validate TLS certificates. This places users of the library with those configurations at risk of man-in-the-middle and information leakage attacks. This vulnerability affects users using versions 1.17 and 1.18 of the urllib3 library, who are using the optional PyOpenSSL support for TLS instead of the regular standard library TLS backend, and who are using OpenSSL 1.1.0 via PyOpenSSL. This is an extremely uncommon configuration, so the security impact of this vulnerability is low. Versiones 1.17 y 1.18 de la librería de Python urllib3 sufren una vulnerabilidad que puede provocarles, en ciertas configuraciones, que no validen correctamente certificados TLS. • http://www.openwall.com/lists/oss-security/2016/10/27/6 http://www.securityfocus.com/bid/93941 • CWE-295: Improper Certificate Validation •
