This vulnerability is due to insufficient validation of user-supplied input. An attacker with valid credentials could exploit this vulnerability by submitting a crafted API request. A successful exploit could allow the attacker to execute commands as the root user. To exploit this vulnerability, the attacker must have valid high-privileged credentials.
