Important Security Update for D-Link Routers

Summary: D-Link released firmware updates on Nov. 28 for several older router models to close a backdoor that let an attacker log in as administrator without authentication by setting the browser's user agent string to "xmlset_roodkcableoj28840ybtide". Researcher Craig Heffner discovered and blogged about the flaw roughly seven weeks earlier, and later posted a proof-of-concept showing attackers could also upload arbitrary code to the vulnerable devices.

What's compelling: The affected routers are old set-it-and-forget-it devices that rarely get replaced or updated, and the flaw was rated 10.0 (HIGH) on the NVD and noted as exploited in the wild in October 2013 - so the population of unpatched units is the exposure, not the patch itself.
