== Sensitive Code Example

Arguments like `-delete` or `-exec` for the `find` command can alter the expected behavior and result in vulnerabilities:
----
String input = request.getParameter("input");
String cmd[] =  new String[] { "/usr/bin/find", input };
Runtime.getRuntime().exec(cmd); // Sensitive
----

== Compliant Solution

Use an allow-list to restrict the arguments to trusted values:
[source,java]
----
String input = request.getParameter("input");
if (allowed.contains(input)) {
  String cmd[] =  new String[] { "/usr/bin/find", input };
  Runtime.getRuntime().exec(cmd);
}
----
