PHP-Fusion BBCode IMG Tag XSS

medium Nessus Plugin ID 17302


The remote web server hosts a PHP script that is prone to cross-site scripting attacks.


The remote host is running a version of PHP-Fusion that does not sufficiently sanitize JavaScript code. Specifically, an attacker can inject JavaScript code that bypasses the filters in 'fusion_core.php' by HTML-encoding it. This code will then be executed in the context of a user's browser when viewing the malicious BBcode on the remote host.


Install the 5.01 Service Pack or upgrade to a newer version of PHP-Fusion.
