Cisco patches serious flaws in cable modems and home gateways

The vulnerabilities could lead to remote code execution, information disclosure or denial of service

Cisco Systems has patched high-impact vulnerabilities in several of its cable modem and residential gateway devices that are distributed by some ISPs to their customers.

The embedded Web server in the Cisco Cable Modem with Digital Voice models DPC2203 and EPC2203 contains a buffer overflow vulnerability that can be exploited remotely without authentication.

The flaw could be exploited by sending specially crafted HTTP requests to the Web server and could result in arbitrary code execution.

Customers should contact their service providers to ensure that the software version installed on their devices includes the patch for this issue, Cisco said in an advisory.

The Web-based administration interfaces of the Cisco DPC3941 Wireless Residential Gateway with Digital Voice and Cisco DPC3939B Wireless Residential Voice Gateway are affected by a vulnerability that could lead to information disclosure.

An unauthenticated, remote attacker could exploit the flaw by sending a specially crafted HTTP request to an affected device in order to obtain sensitive information from it.

The Cisco Model DPQ3925 8x4 DOCSIS 3.0 Wireless Residential Gateway with EDVA is affected by a separate vulnerability, also triggered by malicious HTTP requests, that could lead to a denial-of-service condition.

In recent years, attackers have increasingly targeted modems, routers and other gateway devices, especially those distributed by ISPs to their customers. By compromising such devices, attackers can snoop on, hijack or disrupt network traffic or can attack other devices inside local networks.

Educating from the epicentre - Why distributors are the pulse checkers of the channel

Educating from the epicentre - Why distributors are the pulse checkers of the channel

​As the channel changes and industry voices deepen, the need for clarity and insight heightens. Market misconceptions talk of an “under pressure” distribution space, with competitors in that fateful “race for relevance” across New Zealand. Amidst the cliched assumptions however, distribution is once again showing its strength, as a force to be listened to, rather than questioned. Traditionally, the role was born out of a need for vendors and resellers to find one another, acting as a bridge between the testing lab and the marketplace. Yet despite new technologies and business approaches shaking the channel to its very core, distributors remain tied to the epicentre - providing the voice of reason amidst a seismic industry shift. In looking across both sides of the vendor and partner fences, the middle concept of the three-tier chain remains centrally placed to understand the metrics of two differing worlds, as the continual pulse checkers of the local channel. This exclusive Reseller News Roundtable, in association with Dicker Data and rhipe, examined the pivotal role of distribution in understanding the health of the channel, educating from the epicentre as the market transforms at a rapid rate.
