Description: A vulnerability was reported in SquirrelMail. A remote user can conduct cross-site scripting attacks.
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 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 'mailto' parameter in 'webmail.php' and the 'session' and 'delete_draft'
parameters in 'compose.php' are affected.
The HTML mail viewer is also affected.
