Descriptions
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.
