What are the security implications of running PHP scripts that interact with Powershell commands on a Windows server?

Running PHP scripts that interact with Powershell commands on a Windows server can pose security risks, as it opens up the possibility of command injection attacks if user input is not properly sanitized. To mitigate this risk, it is important to validate and sanitize user input before passing it to Powershell commands. 

$user_input = $_POST['user_input']; // Get user input from form submission
$validated_input = escapeshellarg($user_input); // Validate and sanitize user input

// Execute Powershell command with validated input
$output = shell_exec("powershell.exe -Command 'YourPowershellScript $validated_input'");
echo $output;
