In November, security researchers found a Walmart-branded router called Jetstream contained a way for a third party to remotely control the router and devices connected to it. Walmart responded and said it stopped selling these routers. The manufacturer, Wavlink, also responded. A firmware update includes the following:
Removed unnecessary diagnostic pages; Deleted tcpdump tool; Added codes to block CSRF attack; Improved Web authentication routine.
The researchers haven’t yet tested the update to see if it has been effective.
