A security research found 10 “critical” security flaws in a popular D-Link wireless router. This is not the first time that poor security has painted this company with the ugly stick. They have previously been sued by the Federal Trade Commission, and we have reported about their deficiencies in this blog.
Security researcher Pierre Kim says the D-Link DIR-850L AC1200 Dual Band Gigabit Cloud router has 10 security vulnerabilities serious enough for him to recommend owners to “immediately disconnect vulnerable routers from the internet”.
- No protection for the router’s firmware, allowing an attacker to upload a new image.
- One version has a hard-coded administrative password
- Cross-site scripting (XSS) security flaws.
- Numerous vulnerabilities in cloud protocol implementation
- Some routers have backdoor access
- No authentication protecting DNS configuration, which would allow an attacker to rerout your traffic to malicious sites.
Since this router is no longer in production, the likelihood of a firmware upgrade for this device is low. If you own one of these routers, you should replace it with something newer, better, and not manufactured by D-Link.
