SquirrelMail Input Validation Holes in Multiple Scripts Permit Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1014217
SecurityTracker URL:  http://securitytracker.com/id/1014217
CVE Reference:   CVE-2005-1769   (Links to External Site)
Date:  Jun 16 2005
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): 1.4.0 - 1.4.4
Description:   Some input validation vulnerabilities were reported in SquirrelMail. A remote user can conduct cross-site scripting attacks.

Several scripts do not properly validate user-supplied input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. A remote user can also send 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 addressbook.php, mime.php, page_header.php, calendar.php, day.php, event_create.php, event_edit.php, options.php, spamoptions.php, mailout.php, and newmail.php scripts and other scripts are affected.

The vendor credits Martijn Brinkers with discovering many of these vulnerabilities.

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:   The vendor has released a fixed version (1.4.5 release candidate 1). A patch is also available at:
