Researchers identify 10 security vulnerabilities on Linksys Smart Wi-Fi routers. Six of the security issues we identified allow unauthenticated attackers to create a Denial-of-Service (DoS) condition on the router. Backdoor accounts would not be shown on the web admin interface and could not be removed using the Admin account. We used Shodan to identify vulnerable devices currently exposed on the Internet. Linksys is proactively publishing a security advisory to prevent attackers from exploiting the security vulnerabilities we identified.”]
