Lack of Administrator Control over Security

Description

If the product's administrator does not have the ability to manage security-related decisions at all times, then protecting the product from outside threats - including the product's developer - can become impossible. For example, a hard-coded account name and password cannot be changed by the administrator, thus exposing that product to attacks that the administrator can not prevent.

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

The following code is an example of an internal hard-coded password in the back-end:

int VerifyAdmin(char *password) {

  if (strcmp(password, "Mew!")) {

    printf("Incorrect Password!\n");
    return(0)

  }
  printf("Entering Diagnostic Mode...\n");
  return(1);

}

int VerifyAdmin(String password) {
  if (!password.equals("Mew!")) {
    return(0)
  }
  //Diagnostic Mode
  return(1);
}

Every instance of this program can be placed into diagnostic mode with the same password. Even worse is the fact that if this program is distributed as a binary-only distribution, it is very difficult to change that password or disable this "functionality."
