Two OS command injection vulnerabilities were discovered in the update installation functionality due to insufficient validation of the update bundle contents. An attacker with administrative privileges can remotely supply a crafted update bundle that, when installed, causes arbitrary commands to be executed with root privileges, allowing the attacker to read or modify sensitive data, change the appliance configuration, or shut down the appliance.
