(Conectiva Issues Fix) SquirrelMail Input Validation Hole in 'mime.php' Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1012387
SecurityTracker URL:  http://securitytracker.com/id/1012387
CVE Reference:   CVE-2004-1036   (Links to External Site)
Date:  Dec 2 2004
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): 1.4.3a and earlier; SquirrelMail 1.5.1-cvs before October 23, 2004
Description:   An input validation vulnerability was reported in SquirrelMail in 'mime.php'. A remote user can conduct cross-site scripting attacks.

The vendor reported that the software does not properly validate encoded text in certain headers. A remote user can create specially crafted e-mail that, when viewed by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the SquirrelMail 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 flaw resides in 'mime.php'.

The vendor credits Joost Pol with reporting this flaw.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the SquirrelMail 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:   Conectiva has released a fix.

DESCRIPTION
 SquirrelMail[1] is a widely used webmail client for php4.
 
 Joost Pol noticed[2] that SquirrelMail is prone to a cross site
 scripting issue in the decoding of encoded text in certain headers.
 SquirrelMail correctly decodes the specially crafted header, but
 doesn't sanitize the result.


SOLUTION
 It is recommended that all SquirrelMail users upgrade their
 packages.
