Execution of OS command formed with user input detected.

Description

Applications should not execute OS commands that are formed from user input. This rule checks for external commands containing user-supplied data.

Remediations

❌ Avoid using user input when executing commands:

exec($_GET["command"]);

✅ Use user input indirectly when executing commands:

if ($_GET["action"] == "option1") {
$command = "command1";
} else {
$command = "command2";
}

exec($command);
