Description: rgod reported a vulnerability in CuteNews. A remote user can conduct cross-site scripting attacks. A remote user can also determine the installation path.
The 'login.php' and 'search.php' scripts do not properly filter HTML code from 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.
The code will originate from the site running the CuteNews 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.
Some
demonstration exploit URLs are provided:
http://[target]/[path]/index.php?lastusername='><script>alert(document.cookie)</script><!--
http://[target]/[path]/index.php?
lastusername=%27%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E%3C%21--
http://[target]/[path]/search.php?selected_search_arch=><script>alert(document.cookie)</
script><!--
http://[target]/[path]/search.php?selected_search_arch=%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E%3C%21--
A
remote user can supply the following URL to cause the system to disclose the installation path:
http://[target]/[path]/show_news.php?archive=whathell
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
CuteNews 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.
A remote user can determine the installation path.
