https://notcve.org/view.php?id=CVE-2021-3733
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib. Un atacante que controle un servidor HTTP malicioso al que se conecte un cliente HTTP (como un navegador web), podría desencadenar una Denegación de Servicio por Expresión Regular (ReDOS) durante una petición de autenticación con una carga útil especialmente diseñada que sea enviada por el servidor al cliente. • https://bugs.python.org/issue43075 https://bugzilla.redhat.com/show_bug.cgi?id=1995234 https://github.com/python/cpython/commit/7215d1ae25525c92b026166f9d5cac85fb https://github.com/python/cpython/pull/24391 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://security.netapp.com/advisory/ntap-20220407-0001 https://ubuntu.com/security/CVE-2021-3733 https://access.redhat.com/security/cve/CVE-2021-3733 • CWE-400: Uncontrolled Resource Consumption •
