Powie's PSCRIPT Forum fails to filter user posts

Vulnerability Note VU#674542

Original Release Date: 2004-08-23 | Last Revised: 2004-08-25


Powie's PSCRIPT Forum fails to properly sanitize user input, which allows an attacker to create a user profile that can execute arbitrary scripts in a victim's web browser when the victim views the profile.


Powie's PSCRIPT Forum is an online forum application written in PHP. The application allows users to set up a user profile which may be viewed by other users. A failure to filter input in two fields of the user profile section may permit a malicious user to post HTML/script that will be interpreted by a victim's client.


A malicious user can execute arbitrary HTML/script in the context of the vulnerable web site. If this vulnerability is exploited, a user may be tricked into exposing sensitive information, allowing an attacker to gather information such as passwords and credit card numbers. Information stored in cookies may also be stolen or corrupted.


This issue is resolved in version 1.26 of the forum, available from the download page.
