Official description

A vulnerability in the Connect Mobility Router component of Mitel MiVoice Connect versions 9.6.2208.101 and earlier could allow an unauthenticated attacker with internal network access to authenticate with administrative privileges, because the initial installation does not enforce a password change. A successful exploit could allow an attacker to make arbitrary configuration changes and execute arbitrary commands.

The underlying weakness: Weak Password Recovery Mechanism for Forgotten Password

The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

How developers prevent this class of flaw

  • Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
  • Do not use standard weak security questions and use several security questions.
  • Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
