CVE-2019-14360 : What You Need to Know
Discover the side channel vulnerability on Hyundai Pay Kasse HK-1000 devices affecting the row-based OLED display. Learn about the impact, affected systems, exploitation mechanism, and mitigation steps.
A vulnerability was discovered on Hyundai Pay Kasse HK-1000 devices, specifically affecting the row-based OLED display. This vulnerability allows for partial recovery of display contents by analyzing the power consumption during each display cycle, which depends on the number of illuminated pixels. An unauthorized hardware implant within the USB cable could potentially exploit this behavior to retrieve sensitive information like the PIN and BIP39 mnemonic. However, this side channel vulnerability is only applicable if the attacker has sufficient control over the device's USB connection to measure power consumption while secret data is being displayed.
