"According to its self-reported version, the Cisco Emergency Responder (CER) is affected by a cross-site scripting
vulnerability in the web-based management interface due to insufficient validation of user-supplied input. An
authenticated, remote attacker could exploit this by persuading a user of the interface to click a malicious link or
by intercepting a user request for the affected web interface and injecting malicious code into the request. A
successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web
interface or allow the attacker to access sensitive browser-based information.");
