Remote Data Injection Vulnerability in Arduino Embedded Systems

CVE-2019-13991

What is CVE-2019-13991?

Embedded systems utilizing Arduino technology prior to Rev3 are susceptible to a unique vulnerability that allows remote attackers to control LEDs connected to GPIO pins. By leveraging the photosensitivity of LEDs, an attacker can send data to these light-emitting diodes using a laser, effectively creating a means of unauthorized remote communication. This vulnerability highlights the need for enhanced security measures in embedded systems and careful consideration of hardware design to protect against such attacks.
