FKIE_CVE-2019-18673

Vulnerability from fkie_nvd - Published: 2019-11-02 17:15 - Updated: 2024-11-21 04:33
Severity ?
4.6 (Medium) - CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
On SHIFT BitBox02 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. Note: BIP39 secrets are not displayed by default on this device. 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.

      "value": "En los dispositivos SHIFT BitBox02, se encontr\u00f3 un canal lateral para la pantalla OLED basada en filas. El consumo de energ\u00eda de cada ciclo de visualizaci\u00f3n basado en filas depende del n\u00famero de p\u00edxeles iluminados, permitiendo una recuperaci\u00f3n parcial del contenido de la pantalla. Por ejemplo, un implante de hardware en el cable USB podr\u00eda ser capaz de aprovechar este comportamiento para recuperar secretos confidenciales tales como el PIN y el mnem\u00f3nico BIP39. Nota: los secretos BIP39 no son mostrados por defecto en este dispositivo. El canal lateral es relevante solo si el atacante tiene control suficiente sobre la conexi\u00f3n USB del dispositivo para llevar a cabo mediciones de consumo de energ\u00eda en un momento en que los datos secretos son mostrados. El canal lateral no es relevante en otras circunstancias, tal y como un dispositivo robado que actualmente no muestra datos secretos."
