Test ID:
Category:Web application abuses
Title:MediaWiki Multiple Vulnerabilities - Aug12 (Linux)
Summary:This host is installed with MediaWiki; and is prone to multiple vulnerabilities.
This host is installed with MediaWiki
and is prone to multiple vulnerabilities.

Vulnerability Insight:
Multiple flaws exists due to:

- a Cross-site scripting (XSS) vulnerability that allows remote attackers to inject arbitrary web script or HTML via a File: link to a nonexistent image.

- multiple cross-site scripting (XSS) vulnerabilities, when unspecified JavaScript gadgets are used, allow remote attackers
to inject arbitrary web script or HTML via the userlang parameter to w/index.php.

- MediaWiki not sending a restrictive X-Frame-Options HTTP header, which allows remote attackers to conduct clickjacking attacks via an embedded API response in an IFRAME element.

- MediaWiki allowing remote attackers to bypass GlobalBlocking extension IP address blocking and thus creating an account via unspecified vectors.

- MediaWiki not properly protecting user block metadata, which allows remote administrators to read a user block reason via a reblock attempt.

Vulnerability Impact:
Successful exploitation will allow remote attackers to conduct XSS attacks, affect the application's integrity and
have other some unspecified impact.

Impact Level: Application

Affected Software/OS:
MediaWiki before 1.18.5, and 1.19.x before 1.19.2

Upgrade to version 1.18.5 or 1.19.2 or later. For updates refer https://www.mediawiki.org
