What is CVE-2019-14360?
CVE-2019-14360 is a medium-severity vulnerability in n/a, published on 2 Nov 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
On Hyundai Pay Kasse HK-1000 devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. In other words, the side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data.
