SecurityTracker Alert ID:  1009307
SecurityTracker URL:  http://securitytracker.com/id/1009307
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Updated:  Mar 15 2004
Original Entry Date:  Mar 3 2004
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 1.6.1511 [Also confirmed on 1.6.1529]
Description:   An input validation vulnerability was reported in SmarterMail. A remote user can conduct cross-site scripting attacks.

Dr_insane reported that the spell checking feature does not properly filter HTML code from user-supplied input before displaying the input. As a result, a remote user can create a specially crafted input that, when spell checked by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the mail server site 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 original advisory is available at:
