(Vendor Issues Fix) Re: PHPGroupWare Input Validation Flaws Permit Remote Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1007199
SecurityTracker URL:  http://securitytracker.com/id/1007199
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jul 15 2003
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): 0.9.14.003
Description:   Security Corporation issued a security advisory warning of an input validation vulnerability in PHPGroupWare. A remote user can conduct cross-site scripting attacks.

Francois Sorin reported that several components do not filter HTML code from user-supplied input. All of the additional modules that have forms are reportedly affected.

A remote user can insert specially crafted text into a web form field. Then, when a target user views the information, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running PHPGroupWare 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.

For example, a remote user can place scripting code in the name or surname field when adding a contact.

The following notification timeline is provided:

06/24/2003 Vendor notified
06/25/2003 Vendor response and solutions
07/01/2003 Vendor authorisation
07/01/2003 Security Corporation clients notified
07/02/2003 Public disclosure

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the PHPGroupWare 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 released a fix available via CVS (as of July 3, 2003) for all branches (14, 16preRC and HEAD). The vendor has also issued a fixed version (0.9.14.004), available at:

http://www.phpgroupware.org/downloads/

Vendor URL:  www.phpgroupware.org/ (Links to External Site)
Cause:   Input validation error
Underlying OS:  Linux (Any), UNIX (Any), Windows (Any)
