Arduino up to Rev2 LED Side-Channel information disclosure

A vulnerability classified as problematic has been found in Arduino up to Rev2. Affected is an unknown functionality of the component LED Handler. The manipulation with an unknown input leads to a information disclosure vulnerability (Side-Channel). CWE is classifying the issue as CWE-514. This is going to have an impact on confidentiality. CVE summarizes:

Embedded systems based on Arduino before Rev3 allow remote attackers to send data to LEDs (directly connected to GPIO pins) via a laser, because of LED photosensitivity.

The weakness was shared 07/19/2019. This vulnerability is traded as CVE-2019-13991 since 07/19/2019. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx.
