WRH-733GBK and WRH-733GWH contain an improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in miniigd SOAP service. If a remote unauthenticated attacker sends a specially crafted request to the affected product, an arbitrary OS command may be executed.
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.
