MediaWiki 1.19.x < 1.19.7 / 1.20.x < 1.20.6 Arbitrary File Upload

Medium Nessus Plugin ID 66841


The remote web server contains a PHP application that is affected by an arbitrary upload vulnerability.


According to its version number, the instance of MediaWiki running on the remote host is affected by an arbitrary file upload vulnerability due to a flaw that fails to validate file extensions when files are uploaded via chunks using the API.

Note that Nessus has not tested for this issue but has instead relied on the application's self-reported version number.


Upgrade to MediaWiki version 1.19.7 / 1.20.6 or later.
