Cisco Systems is offering a patch for a flaw in the second version of its Wireless-G broadband router, model number WRT54G, which it is claimed can allow hackers access to home networks. The device, reviewed in the current issue of Windows Middle East magazine, was found by an independent security consultant to contain a flaw that could give hackers free rein over home users' machines. Security consultant Alan Rateliff II discovered the issue, which he claims allows cyber vandals to freely access the online configuration page of the router when its firewall function is switched off. This could lead to hackers being able to launch virus and spam attacks, and access devices connected to a home network such as notebooks and PCs. The problem centres around version 2.02.7 of the router’s firmware. When the device’s firewall function is turned off, Rateliff claims the firmware allows access to a user’s web-based configuration page through ports 80 and 443. "It's like giving a hacker a key to a locked door," Rateliff was quoted as saying. "There's no telling what he will do once he's inside. The scenarios are only limited by what we can imagine." Cisco has immediately responded to the problem by posting a beta (or trial) version of new firmware for the router, available from the Download section of its Linksys web site at www.linksys.com.
