4.6 mediumCVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVE-2019-17391
Medium (4.6) in espressif. EPSS 0.2% chance of exploitation in the next 30 days.
An issue was discovered in the Espressif ESP32 mask ROM code 2016-06-08 0 through 2. Lack of anti-glitch mitigations in the first stage bootloader of the ESP32 chip allows an attacker (with physical access to the device) to read the contents of read-protected eFuses, such as flash encryption and secure boot keys, by injecting a glitch into the power supply of the chip shortly after reset.
