Impact: Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information

Version(s): 2.1 and prior versions

Description: A vulnerability was reported in PHP iCalendar. A remote user can conduct cross-site scripting attacks.
The 'rss/index.php' script does not properly filter HTML code from user-supplied input in the 'cal' parameter before displaying the
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. The code will originate from the site running the PHP iCalendar 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.
A demonstration exploit URL is provided:
http://[target]/phpicalendar/rss/index.php?cal=[XSS]

Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
