conexant adsl router backdoor

[Luca Bartolomai <mefistofle@xxxxxxxxx>]

Hi ,

I have acquired one router adsl conexant model Trident .

This modem is identical to the Italian version Digicom Michelangelo Office, 

but the firmware is modding .

If get file CONFIG.REG from ftp modem server and edit it , you can see this 

DWORD :

[Class\Protocol\Bridge\0000]

"DeviceId"=dword:00000000

"BackDoorEnabled"=dword:00000001

"EthernetFilterEnabled"=dword:00000000

"OutputProcessingEnabled"=dword:00000000

"SubnetMuxEnabled"=dword:00000001



BackDoorEnabled ?  what is ?



I'am scaned with nmap but not found particular listen port .

it is a backdoor on ATM ?

I will continue to inquire 



Best regards 



Jack
