Detailsinfo

A vulnerability classified as problematic has been found in MediaWiki 1.19.9/1.21.3/1.22.0 (Content Management System). This affects some unknown processing of the file User.php of the component Authentication. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality. The summary by CVE is:

includes/User.php in MediaWiki before 1.19.12, 1.20.x and 1.21.x before 1.21.6, and 1.22.x before 1.22.3 terminates validation of a user token upon encountering the first incorrect character, which makes it easier for remote attackers to obtain access via a brute-force attack that relies on timing differences in responses to incorrect token guesses.

The weakness was released 03/02/2014 by Mario Gomes as MediaWiki Security and Maintenance Releases: 1.22.3, 1.21.6 and 1.19.12 as confirmed posting (Mailing List). The advisory is shared at lists.wikimedia.org. This vulnerability is uniquely identified as CVE-2014-2243 since 02/28/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. CVE summarizes: "MediaWiki (…) terminates validation of a user token upon encountering the first incorrect character, which makes it easier for remote attackers to obtain access via a brute-force attack that relies on timing differences in responses to incorrect token guesses."
