MediaWiki Multiple Bugs Let Remote Users Obtain Potentially Sensitive Information and Conduct Cross-Site Scripting Attacks and Let Remote Authenticated Users Bypass Security and Deny Service
SecurityTracker Alert ID:  1034028
SecurityTracker URL:  http://securitytracker.com/id/1034028
CVE Reference:   CVE-2015-8001, CVE-2015-8002, CVE-2015-8003, CVE-2015-8004, CVE-2015-8005, CVE-2015-8006, CVE-2015-8007, CVE-2015-8008, CVE-2015-8009   (Links to External Site)
Date:  Oct 29 2015
Impact:   Denial of service via network, Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): prior to versions 1.23.11, 1.24.4, 1.25.3
Description:   Multiple vulnerabilities were reported in MediaWiki. A remote authenticated user can consume excessive memory on the target system. A remote user can determine the installation path. A remote authenticated user can obtain potentially sensitive information on the target system. A remote authenticated user can bypass security restrictions. A remote user can conduct cross-site scripting attacks.

A remote authenticated user can invoke the API and add infinite new chunks to the upload even if the reported size is exceeded [CVE-2015-8001].

A remote authenticated user can upload chunks that are one byte in size for a very large file to consume an excessive number of files on the target system [CVE-2015-8002].

A remote authenticated user can upload files without being throttled [CVE-2015-8003].

A remote authenticated user with 'viewsuppressed' privileges but not 'suppressrevision' privileges can unsupress revisions [CVE-2015-8004].

Thumbnails of PNG files generated via ImageMagick include the local file path in the image metadata [CVE-2015-8005].

The 'Extension:PageTriage' extension does not properly filter HTML code from user-supplied input in page titles before displaying the input [CVE-2015-8006]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the MediaWiki software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

The 'Extension:Echo' extension may display deleted or suppressed usernames when the username was previously used to thank users [CVE-2015-8007]. A remote authenticated user may view certain usernames.

A remote authenticated user can bypass IP-based access restrictions in the 'Extension:OAuth' extension by using previously negotiated credentials [CVE-2015-8008].

A remote authenticated user with access to a target user's access tokens and secrets can exploit a signature validation flaw in the 'Extension:OAuth' extension to use the credentials [CVE-2015-8009].

Richard Stanway from teamliquid.net and Wikipedia users RobinHood70, Sitic, and Grunny reported these vulnerabilities.

Impact:   A remote authenticated user can consume excessive file resources on the target system.

A remote user can determine the installation path.

A remote authenticated user can obtain potentially sensitive information on the target system.

A remote authenticated user can bypass security controls on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the MediaWiki software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fix (1.23.11, 1.24.4, 1.25.3).
Vendor URL:  www.mediawiki.org/ (Links to External Site)
Cause:   Access control error, Authentication error, Input validation error
Underlying OS:  Linux (Any), UNIX (Any), Windows (Any)

Message History:   None.
