CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2019-11324 – python-urllib3: Certification mishandle when error should be thrown
https://notcve.org/view.php?id=CVE-2019-11324
The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument. La urllib3 library versión anterior a 1.24.2 para Python maneja de forma incorrecta ciertos casos en los que el ajuste deseado de certificados de CA es diferente del almacén del sistema operativo de certificados de CA, lo que da como resultado que las conexiones SSL tengan éxito en situaciones en las que una falla de comprobación sea el resultado correcto. Esto está relacionado con el uso de los argumentos ssl_context, ca_certs o ca_certs_dir. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00041.html http://www.openwall.com/lists/oss-security/2019/04/19/1 https://access.redhat.com/errata/RHSA-2019:3335 https://access.redhat.com/errata/RHSA-2019:3590 https://github.com/urllib3/urllib3/compare/a6ec68a...1efadf4 https://lists.debian.org/debian-lts-announce/2021/06/msg00015.html https://lists.debian.org/debian-lts-announce/2023/1 • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2019-11236
In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter. En la librería urllib3, hasta la versión 1.24.1 para Python, se puede realizar una inyección CRLF si el atacante controla el parámetro request. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00041.html https://access.redhat.com/errata/RHSA-2019:2272 https://access.redhat.com/errata/RHSA-2019:3335 https://access.redhat.com/errata/RHSA-2019:3590 https://github.com/urllib3/urllib3/issues/1553 https://lists.debian.org/debian-lts-announce/2019/06/msg00016.html https://lists.debian.org/debian-lts-announce/2021/06/msg00015.html https:// • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
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 •
