The underlying weakness: Unverified Password Change

When setting a new password for a user, the product does not require knowledge of the original password, or using another form of authentication.

How developers prevent this class of flaw

  • When prompting for a password change, force the user to provide the original password in addition to the new password.
  • Do not use forgotten password functionality. But if you must, ensure that you are only providing information to the actual user, e.g. by using an email address or challenge question that the legitimate user already provided in the past; do not allow the current user to change this identity information until the correct password has been provided.
