Are there any security risks or vulnerabilities associated with using system commands in PHP to retrieve sensitive information like network usage data?

Using system commands in PHP to retrieve sensitive information like network usage data can pose security risks, such as command injection attacks. To mitigate this risk, it is recommended to use PHP functions like `exec()` with proper input validation and sanitization to prevent malicious commands from being executed. 

$command = 'netstat -an';
$output = shell_exec(escapeshellcmd($command));

echo $output;
