Descriptions

The CentralAuth extension for MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 caches a valid CentralAuthUser object in the centralauth_User cookie even when a user has not successfully logged in, which allows remote attackers to bypass authentication without a password.

La extensión de MediaWiki CentralAuth 1.19.x anterior a 1.19.8, 1.20.7 anterior a 1.20.x y 1.21.x anterior 1.21.2 almacena en caché un objeto CentralAuthUser válida en la cookie centralauth_User incluso cuando el usuario no ha iniciado la sesión correctamente, lo que permite atacantes remotos evitar la autenticación sin contraseña.

Multiple vulnerabilities have been found in MediaWiki, the worst of which could lead to Denial of Service. Versions less than 1.21.2 are affected.
