This is a typical example of a hardcoded password that users have no way of changing. The password itself is not the main security issue with this device.
The problem is that the password is hardcoded into the device's operating system. This means that even with a locked bootloader, it would still be possible to flash another operating system. This was made even easier due to the fact that the kernel and rootfs are stored in the device's memory. In the worst case scenario, an attacker could flash a malicious kernel and load arbitrary rootfs.
Conclusion: Hardcoded passwords should be avoided
Hardcoded passwords should be avoided because they are easily guessable and attackers can crack them. Hardcoded passwords also prevent users from being able to change the password themselves, which is a security issue in its own right.
Weak usernames and passwords
The problem here is that the device uses weak usernames and passwords. These are easily guessed by brute force attacks because they use predictable language, such as "admin" and "password." Additionally, these devices have default settings which allows connections to be made with the network at all times. If a user managed to connect his or her phone with a network, an attacker could potentially access the device.
If you own one of these devices, you should change your password immediately. There is no way of changing the password remotely without physical intervention or factory-resetting the device.
