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 •

https://notcve.org/view.php?id=CVE-2018-1000808
Python Cryptographic Authority pyopenssl version Before 17.5.0 contains a CWE - 401 : Failure to Release Memory Before Removing Last Reference vulnerability in PKCS #12 Store that can result in Denial of service if memory runs low or is exhausted. This attack appear to be exploitable via Depends upon calling application, however it could be as simple as initiating a TLS connection. Anything that would cause the calling application to reload certificates from a PKCS #12 store.. This vulnerability appears to have been fixed in 17.5.0. Python Cryptographic Authority pyopenssl en versiones anteriores a la 17.5.0 contiene una vulnerabilidad CWE - 401: Error al liberar memoria antes de eliminar la última referencia en PKCS #12 Store que puede resultar en una denegación de servicio (DoS) si hay poca memoria o ésta se agota. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00014.html https://access.redhat.com/errata/RHSA-2019:0085 https://github.com/pyca/pyopenssl/pull/723 https://usn.ubuntu.com/3813-1 https://access.redhat.com/security/cve/CVE-2018-1000808 https://bugzilla.redhat.com/show_bug.cgi?id=1640216 • CWE-400: Uncontrolled Resource Consumption CWE-404: Improper Resource Shutdown or Release •
