Description

This module exploits an option injection vulnerability in the SyntaxHighlight
extension of MediaWiki. It tries to create & execute a PHP file in the document root.
The USERNAME & PASSWORD options are only needed if the Wiki is configured as private.

This vulnerability affects any MediaWiki installation with SyntaxHighlight version 2.0
installed & enabled. This extension ships with the AIO package of MediaWiki version
1.27.x & 1.28.x. A fix for this issue is included in MediaWiki version 1.28.2 and
version 1.27.3.
