User input is inserted as text into a shell command. The shell may interpret special characters in the input as part of the command.

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

1const host = req.body.host;2exec("ping -c 1 " + host, onResult);

1const host = req.body.host;2if (!/^[a-z0-9.-]{1,253}$/i.test(host)) return res.sendStatus(400);3execFile("ping", ["-c", "1", host], onResult);
