CWE-362Published: September 12, 2018· Updated: Jun 17, 2026

4.6
CVSS v3.1

Official Description

Incorrect access control in RDP Level 1 on STMicroelectronics STM32F0 series devices allows physically present attackers to extract the device's protected firmware via a special sequence of Serial Wire Debug (SWD) commands because there is a race condition between full initialization of the SWD interface and the setup of flash protection.
