Input passed to the "error[]" parameter in index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Successful exploitation requires that "register_globals" is enabled. The vulnerability is reported in version 1.0f. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised. Set "register_globals" to "Off".
