Drupal Core Bugs Let Remote Users Conduct Cross-Site Scripting, Cross-Site Request Forgery, and Open Redirect Attacks
SecurityTracker Alert ID:  1029386
SecurityTracker URL:  http://securitytracker.com/id/1029386
CVE Reference:   CVE-2013-6385, CVE-2013-6386, CVE-2013-6387, CVE-2013-6388, CVE-2013-6389   (Links to External Site)
Date:  Nov 22 2013
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6.x prior to 6.29, 7.x prior to 7.24
Description:   Sevearl vulnerabilities were reported in Drupal. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks.

The Form API does not properly validate user-supplied input. A remote user can take actions on the site acting as the target user [CVE-2013-6385].

A weakness in generating pseudorandom numbers using mt_rand() may cause ostensibly random numbers to be predictable [CVE-2013-6386].

Several scripts do 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 Drupal 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 Image module [CVE-2013-6387] and the Color module [CVE-2013-6388] are affected.

A remote user can cause the target user's browser to redirect to an arbitrary web site [CVE-2013-6389].

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Drupal 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.

A remote user can redirect the target user to an arbitrary web site.

Solution:   The vendor has issued a fix (6.29, 7.24).

The vendor's advisory is available at:
