Updating firmware for linksys
The report comes not long after word surfaced of other security vulnerabilities found in routers made by Linksys' former parent company, Cisco.
Those flaws affected a number of small business products from Cisco, and did not impact any Linksys branded devices.

Johannes Ullrich, chief research officer with the SANS Institute, told The Reg that in addition to updating firmware, owners and administrators of the vulnerable routers should look to tighten their administrator access controls.
