Descriptions

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.

Una vulnerabilidad en la aplicación Device Management Servlet application of Cisco BroadWorks Application Delivery Platform y Cisco BroadWorks Xtended Services Platform podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a una validación de entrada incorrecta al analizar solicitudes HTTP. Un atacante podría aprovechar esta vulnerabilidad enviando un flujo sostenido de solicitudes manipuladas a un dispositivo afectado. Un exploit exitoso podría permitir al atacante provocar que se eliminen todas las solicitudes posteriores, lo que resultaría en una condición DoS.
