<bug_description>The Cisco 675 is vulnerable to a remote Denial of Service attack. An attacker may crash the device by sending the HTTP request "GET ?" to the HTTP port tcp/80 of the router. You need to reboot the device to make it work again.</bug_description>
<bug_solution>Upgrade your Cisco firmware and filter incoming traffic on port tcp/80. As workaround (disabling the web service) you could add the rule "set web disabled", "write" and "reboot" into your device.</bug_solution>
