A number of security flaws in the default firmware and web interface app of a popular router were discovered by CyberNews researchers that could expose its owners at risk of man-in-the-middle and denial-of-service attacks.
TP-Link AC1200 Archer C50 (v6) is a best-selling ‘Amazon’s Choice’ wifi router retails for £34.50 (~$48) in the UK, mainly sold within the European market. Unfortunately, the device is shipped with an outdated firmware version susceptible to numerous security flaws. Not only is the router sold with vulnerable firmware but it also comes with another critical issue that concerns its web interface app. The app “suffers from subpar security practices and weak encryption,” potentially exposing thousands of owners at risk of attacks.
Owners of the TP-Link AC1200 Archer C50 (v6) router should install the latest firmware update immediately.
