CreaDirectory 1.2 - 'addlisting.asp?cat' Cross-Site Scripting

source: https://www.securityfocus.com/bid/21230/info
 
Creascripts creadirectory is prone to multiple input-validation vulnerabilities, inculding SQL-injection issues and a cross-site scripting issue, because the application fails to sufficiently sanitize user-supplied data.
 
Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database implementation.
 
Version 1.2 is vulnerable; other versions may also be affected.
