Some Belkin home routers contain a number of vulnerabilities that could allow an attacker to spoof DNS responses, intercept credentials sent in cleartext, access the web management interface, and take other actions on vulnerable routers. The vulnerabilities affect the Belkin N600 Wireless Dual Band N+ router, model F9K1102 v2 with firmware version 2.10.17, and potentially earlier versions of the firmware, as well. CERT/CC says there aren t any practical workarounds for them.
