Demo Examples

Incorrect Authorization

CWE-863

The following code could be for a medical records application. It displays a record to already authenticated users, confirming the user's authorization using a value stored in a cookie.


               
}
}
setcookie("role", $role, time()+60*60*2);
die("\n");
DisplayMedicalHistory($_POST['patient_ID']);
die("You are not Authorized to view this record\n");

The programmer expects that the cookie will only be set when getRole() succeeds. The programmer even diligently specifies a 2-hour expiration for the cookie. However, the attacker can easily set the "role" cookie to the value "Reader". As a result, the $role variable is "Reader", and getRole() is never invoked. The attacker has bypassed the authorization system.
