Description
A vulnerability in the Device Management Servlet application of Cisco BroadWorks Application Delivery Platform and Cisco BroadWorks Xtended Services Platform could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper input validation when parsing HTTP requests. An attacker could exploit this vulnerability by sending a sustained stream of crafted requests to an affected device. A successful exploit could allow the attacker to cause all subsequent requests to be dropped, resulting in a DoS condition.
