I have a DIR-600 C1 running the latest available firmware version (3.03).
Model: DIR-600
Hardware Version: C1
Firmware Version: 3.03
WiFi Protected Setup is turned ON.
I would like to know if it is affected by the new disclosed vulnerability described here: http://www.kb.cert.org/vuls/id/723755
Also, turning WiFi Protected Setup OFF may not help to mitigate this vulnerability, according to this article: http://arstechnica.com/business/news/2012/01/hands-on-hacking-wifi-protected-setup-with-reaver.ars
Thank you for your attention.
