Supervisor password:


The B10B has an autogenerated supervisor password (hashed from the serial number). Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 introduced these being stored in /etc/shadow. You may have some success reading this file by logging into the router as the "admin" user via SSH. You will need to crack the hash (eg with hashcat), the password will be 8 characters long using characters 0-9,a-f (lower case)

Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 changed to a SHA-512 type hash stored in /etc/shadow. Prior to firmware AAVF.10 you will be able to read /etc/passwd by logging into the router as the "admin" user via SSH or Telnet. With firmware AAVF.10 and later you would have to log in as the supervisor user - but you'd need to know the password....
