Detailsinfo

A vulnerability was found in ShapeShift KeepKey (affected version unknown) and classified as problematic. Affected by this issue is an unknown functionality of the component OLED Display. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

** DISPUTED ** On ShapeShift KeepKey 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 secret data shown on the display. 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. NOTE: the vendor's position is that there is "insignificant risk."

The weakness was shared 08/10/2019. This vulnerability is handled as CVE-2019-14355 since 07/28/2019. The exploitation is known to be difficult. The attack needs to be approached locally.
