Joomla! Bugs Let Remote Users Access Data and Conduct Cross-Site Request Forgery and Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1036552
SecurityTracker URL:  http://securitytracker.com/id/1036552
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Aug 6 2016
Impact:   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  
Version(s): 1.6.0 through 3.6.0
Description:   Several vulnerabilities were reported in Joomla!. A remote user can conduct cross-site request forgery attacks. A remote user can access data on the target system. A remote user can conduct cross-site scripting attacks.

A remote user can create a specially crafted HTML page or URL that, when loaded by the target authenticated user, will exploit a flaw in com_joomlaupdate to take actions on the target interface acting as the target user. Version 3.6.0 is affected.

A remote user can exploit an access control flaw in com_content to gain read access to data that is ostensibly restricted to users with the edit_own privilege on the target system.

The mail component does not properly filter HTML code from user-supplied input before displaying the input. 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 Joomla! 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.

T-Systems Multimedia Solutions, Dingjie (Daniel) Yang, and Calum Hutton reported these vulnerabilities.

Impact:   A remote user can take actions on the target system acting as the target authenticated user.

A remote user can obtain data 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 Joomla! 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 (3.6.1).

The vendor advisory is available at:

Vendor URL:  developer.joomla.org/security-centre.html (Links to External Site)
Cause:   Access control error, Input validation error
