Future Internet - 'index.cfm?categoryId' Cross-Site Scripting

source: https://www.securityfocus.com/bid/21727/info
 
Future Internet is prone to multiple input-validation vulnerabilities, including cross-site scripting and SQL-injection issues, because it fails to sufficiently sanitize user-supplied input.
 
An attacker could exploit these issues to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database implementation.
