Two vulnerabilities have been reported in PHP-Fusion, which can be exploited by malicious people to manipulate the view of the web site interface and conduct SQL injection attacks.

1) Input passed to the BBcode "color" tag is not properly verified before being used in a post. This can be exploited to inject certain CSS (Cascading Style Sheets) code, which will be rendered in a user's browser session in context of an affected site when the malicious post is viewed (e.g. place links in arbitrary positions of the web site outside the post area via the "position" CSS element).

NOTE: The "expression()" function supported by Microsoft Internet Explorer is filtered out by PHP-Fusion.

The vulnerability has been confirmed in version 6.00.106. Other versions may also be affected.

2) Input passed to the "pm_email_notify" and "pm_save_sent" parameters in "messages.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

The vulnerability has been reported in versions 6.00.106 and 6.00.107. Other versions may also be affected.
