MediaWiki < 1.36.0 Invalid MediaWiki Abusefilter-blocker Breaks Filters

Synopsis

MediaWiki < 1.36.0 Invalid MediaWiki Abusefilter-blocker Breaks Filters

Description

According to its self-reported version number, the instance of MediaWiki hosted on the remote web server is prior to 1.36. It is, therefore, affected by a flaw when the blocker message is invalid in the content language, but also English is invalid on the wiki, which may permit remote attackers to bypass restrictions against abusive users.

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 1.36.0 or later.
