CVE-2013-4874


TITLE

Verizon Wireless Network Extender multiple vulnerabilities

Trust: 0.8

sources: CERT/CC: VU#458007

DESCRIPTION

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. iSEC Partners has reported that the Verizon Wireless Network Extender models SCS-26UC4 and SCS-2U01 made by Samsung are susceptible to a local compromise using a custom HDMI cable. Once compromised the device can be used to eavesdrop on voice, text and data communication for mobile devices that connect to the Network Extender. The Verizon Wireless Network Extender is a low-power cellular base station that provides Internet services using an Internet connection. The Verizon Wireless Network Extender has multiple security vulnerabilities to increase permissions or clone other user phones. Use a special console cable to connect to the device and submit a special command sequence to get the root shell. Use the SysReq (System Request) interrupt to gain access to the console and obtain the root shell. In addition, Network Extender does not use Cellular Authentication and Voice Encryption (CAVE) authentication. For mobile phone authentication, the device only uses ESN and MIN. These numbers can physically access the phone or sniff the registration message sent to Network Extender for acquisition. Defects and incorrect validation can be done by running custom code on the Network Extender and going to any phone's ESN and MIN, using these numbers to clone the phone without physical access. A local attacker exploits the vulnerability to escalate permissions and clones the phone. Attackers can use these vulnerabilities to execute arbitrary code with elevated privileges and take complete control of the device. This BID is being retired
