There are multiple vulnerabilities in the Netgear Push2TV (PTV3000)
- Connecting to the UART per the input above, press the spacebar while booting to interrupt the bootloader, U-Boot. From here you can execute your own bootloader commands. "setenv bootargs init=/bin/sh" will drop you to a root shell
- If you miss that, via UART again, a root console is active for 2-3 seconds after booting. As long as you enter your commands while it boots, they will be executed.
- There is also a command injection in the web interface. By inserting a command in the box nickname field (say ;reboot;) the command will be executed as root.
- Finally, the SPI flash chip holds the U-Boot environment, it can be reflashed to load a modified environment
