Summary
========

A vulnerability in the web-based administration interface of Cisco Model 
DPQ3925 8x4 DOCSIS 3.0 Wireless Residential Gateway with EDVA could allow an 
unauthenticated, remote attacker to cause the device to become unresponsive and 
restart, creating a denial of service (DoS) condition.
 
The vulnerability is due to improper handling, processing, and termination of 
HTTP requests. An attacker could exploit this vulnerability by sending crafted 
HTTP requests to management-enabled interfaces of an affected system.


Cisco has released software updates to its service provider customers that 
address the vulnerability described in this advisory. Prior to contacting Cisco 
TAC, customers are advised to contact their service providers to confirm the 
software deployed by the service provider includes the fix that addresses this 
vulnerability. Workarounds that mitigate this vulnerability are not available.
