The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple authenticated operating system (OS) command injection vulnerabilities exist in Firewalla Box Software versions before 1.979. A physically close attacker that is authenticated to the Bluetooth Low-Energy (BTLE) interface can use the network configuration service to inject commands in various configuration parameters including networkConfig.Interface.Phy.Eth0.Extra.PingTestIP, networkConfig.Interface.Phy.Eth0.Extra.DNSTestDomain, and networkConfig.Interface.Phy.Eth0.Gateway6. Additionally, because the configuration can be synced to the Firewalla cloud, the attacker may be able to persist access even after hardware resets and firmware re-flashes.
