osCMax 2.5 - '/admin/xsell.php?search' Cross-Site Scripting

source: https://www.securityfocus.com/bid/52886/info
  
osCMax is prone to multiple SQL-injection vulnerabilities and multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied input.
  
Exploiting these vulnerabilities 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.
  
osCMax 2.5.0 is vulnerable; prior versions may also be affected.
