At least 12 million routers from 50 manufacturers have a flaw that can be exploited by an attacker. The vulnerability is called the “Misfortune Cookie” flaw in RomPager, a Web server that’s embedded in the firmware that runs many router and gateway devices. Devices at risk are at least 200 different products manufactured by such vendors as D-Link, Edimax, Huawei, TP-Link and ZTE. Some manufacturers are continuing to ship products that include a version of Rompager that is a decade or more out of date.”]
