Vulnerabilidades do Blurams Dome Flare Firmware

An insecure authentication mechanism in the safe_exec.sh startup script of Blurams Flare Camera version 24.1114.151.929 and earlier allows an attacker with physical access to the device to execute arbitrary commands with root privileges, if file /opt/images/public_key.der is not present in the file system. The vulnerability can be triggered by providing a maliciously crafted auth.ini file on the device's SD card.

A vulnerability in the boot process of Blurams Flare Camera version 24.1114.151.929 and earlier allows a physically proximate attacker to hijack the boot mechanism and gain a bootloader shell via the UART interface. This is achieved by inducing a read error from the SPI flash memory during the boot, by shorting a data pin of the IC to ground. An attacker can then dump the entire firmware, leading to the disclosure of sensitive information including cryptographic keys and user configurations.
