Description: An input validation vulnerability was reported in PHP Code Snippet Library. A remote user can conduct cross-site scripting attacks.
Nikkyt0x reported that the software does not properly filter HTML code from user-supplied input in the 'cat_select' and 'show' parameters.
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 Code Snippet Library 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?cat_select=[XSS]
http://[target]/[pat
h]/index.php?cat_select=[XSS]&show=[XSS]
