Description: rgod reported a vulnerability in NETonE's phpBook guestbook software. A remote user can conduct cross-site scripting attacks.
The 'guestbook.php' script does not properly filter HTML code from user-supplied input in the 'admin' parameter. 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 phpBook 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]/[path]/guestbook.php?admin="><script>alert(document.cookie)</script><!--
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
phpBook 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.
