"Users who have the option of doing so should strongly consider discontinuing use of affected devices until a fix is made available."Īdministrators, meanwhile, are less than thrilled with Netgear for its security miscue.Īre you shitting me (Exploit by /Y6hLuF0AEv "Exploiting this vulnerability is trivial," the security bods caution. By convincing a user to visit a specially crafted website, a remote unauthenticated attacker may execute arbitrary commands with root privileges on affected routers. Netgear R7000, firmware version 1.0.7.2_1.1.93 and possibly earlier, and R6400, firmware version 1.0.1.12_1.0.11 and possibly earlier, contain an arbitrary command injection vulnerability. US-CERT says an exploit targeting the flaw has already been publicly disclosed. So, for example, if one of the affected models is usually on the local IP address 192.168.0.1, then the following HTML embedded in a webpage will force a reboot when someone on the LAN visits that page – effectively creating a denial-of-service: The web server code executes the given command string effectively as the root user the underlying operating system is BusyBox Linux.

That means that when you connect to the router with WiFi, you see only one 5 GHz SSID that connects to both 5 GHz radio bands. Your router uses Smart Connect to choose the best radio band for your device to give you the best WiFi performance.įor Smart Connect to work, both 5 GHz radio bands must use the same WiFi network name (SSID) and network key (password). Smart Connect balances your 5 GHz WiFi connections into two different radio bands: the 5 GHz radio 1 band and the 5 GHz radio 2 band.
