Advisory Details

This vulnerability allows local attackers to escalate privileges on affected installations of CarlinKit CPC200-CCPA devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the configuration of the application system-on-chip (SoC). The issue results from the lack of a properly configured hardware root of trust. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the boot process.
