CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2019-11324 – python-urllib3: Certification mishandle when error should be thrown
https://notcve.org/view.php?id=CVE-2019-11324
18 Apr 2019 — 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 diferent... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html • CWE-295: Improper Certificate Validation •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 1CVE-2019-11236 – python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service
https://notcve.org/view.php?id=CVE-2019-11236
15 Apr 2019 — 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. It was discovered that urllib3 incorrectly removed Authorization HTTP headers when handled cross-origin redirects. This could result in credentials being sent to unintended hosts. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html • 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
11 Dec 2018 — 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 crede... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html • CWE-522: Insufficiently Protected Credentials •

11 Jan 2017 — 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 ... • http://www.openwall.com/lists/oss-security/2016/10/27/6 • CWE-295: Improper Certificate Validation •
