18 | 1 | Karsten | The RTS5822 supports an internal MCU program ROM, external NOR-Flash interface, and external Serial-Flash interface. With the external Serial-Flash interface, the internal program ROM can be fully replaced and the control firmware can be easily accessed via the USB link. |
19 | 1 | Karsten | * Chip can be used with internal ROM only |
20 | 1 | Karsten | * Hacking the firmware probably allows disabling the recording LED (but this may also be possible by hacking the driver only) |
21 | 1 | Karsten | * We could dump the flash contents to check the firmware |
22 | 1 | Karsten | * Particular webcam has an SPI flash |
23 | 1 | Karsten | => %{color:red}most likely vulnerable%. |
