HTTP D-Link Routers Backdoor Scanner Detail

Detects a firmware backdoor on some D-Link routers by changing the User-Agent to a "secret" value. Using the "secret" User-Agent bypasses authentication and allows admin access to the router.

The following router models are likely to be vulnerable: DIR-100, DIR-120, DI-624S, DI-524UP, DI-604S, DI-604UP, DI-604+, TM-G5240

In addition, several Planex routers also appear to use the same firmware: BRL-04UR, BRL-04CW
