Descriptions

A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.

Se descubrió una regresión de seguridad de CVE-2019-9636 en python desde commit con ID d537ab0ff9767ef024f26246899728f0116b1ec3 que afecta a las versiones 2.7, 3.5, 3.6, 3.7 y de v3.8.0a4 a v3.8.0b1, el cual permite a un atacante explotar CVE-2019-9636 violando las partes usuario (user) y contraseña (password) de una URL. Cuando una aplicación analiza las URL proporcionadas por el usuario para almacenar cookies, credenciales de autenticación u otro tipo de información, es posible que un atacante proporcione URL especialmente creadas para que la aplicación ubique información relacionada con el host (por ejemplo, cookies, datos de autenticación) y envíe a un host diferente al que debería, a diferencia de si las URL se analizaron correctamente. El resultado de un ataque puede variar según la aplicación.
