Hero Framework - 'search?q' Cross-Site Scripting

source: https://www.securityfocus.com/bid/57035/info

Hero is prone to multiple cross-site scripting vulnerabilities and a cross-site request-forgery vulnerability.

An attacker can exploit these vulnerabilities to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, disclose or modify sensitive information, or perform unauthorized actions. Other attacks are also possible.

Hero 3.76 is vulnerable; other versions may also be affected.
