Function Call With Incorrect Variable or Reference as Argument

Demonstrations

The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.

Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.

Example One

In the following Java snippet, the accessGranted() method is accidentally called with the static ADMIN_ROLES array rather than the user roles.

private static final String[] ADMIN_ROLES = ...;
public boolean void accessGranted(String resource, String user) {
  String[] userRoles = getUserRoles(user);
  return accessGranted(resource, ADMIN_ROLES);
}

private boolean void accessGranted(String resource, String[] userRoles) {


  // grant or deny access based on user roles
  ...

}
