Synopsis

MediaWiki 1.37.x < 1.37.1 Multiple Vulnerabilities

Description

According to its self-reported version number, the instance of MediaWiki hosted on the remote web server is prior to 1.35.5, 1.36.x prior to 1.36.3 or 1.37 prior to 1.37.1, It is, therefore, affected by a number of vulnerabilities as follows.

- A vulnerability in the date validation functions of Special:CheckUserLog enabling XSS attacks.

- A flaw with length validation routines in Language Name Search in api.php leading to a denial of service when a very long key is used in the search.

- A flaw in MassEditRegex whereby it does not correctly check for CSRF tokens making it vulnerable to attack.

- A vulnerability in WikibaseMediaInfo's handling of caption fields enabling XSS attacks.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MediaWiki version 1.37.1 or later.
