Input passed to the "number", "bg", and "f" parameters 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. The vulnerabilities are confirmed in version 3.1.8. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised.
