Vulnerability CVE-2013-4304 - CERT Civis.Net

Vulnerability Name:

CVE-2013-4304 (CCN-86894)

Assigned:

2013-09-03

Published:

2013-09-03

Updated:

2017-08-29

Summary:

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.
