Verizon Wireless Network Extender scs-26uc4

The Uboot bootloader on the Verizon Wireless Network Extender SCS-26UC4 allows physically proximate attackers to obtain root access by connecting a crafted HDMI cable and using a sys session to modify the ramboot environment variable.

The Verizon Wireless Network Extender SCS-26UC4 and SCS-2U01 does not use CAVE authentication, which makes it easier for remote attackers to obtain ESN and MIN values from arbitrary phones, and conduct cloning attacks, by sniffing the network for registration packets.
