A weakness has been identified in Edimax EW-7438RPn up to 1.31. The affected element is the function formWpsStart of the file /goform/formWpsStart of the component webs. This manipulation of the argument pinCode causes os command injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
