Unauthenticated access to user or admin accounts

Published Jan 15, 2026 · Updated Jan 15, 2026

Authentication bypass in Mitel MiVoice MX-ONE 7.3 through 7.8 SP1 allows remote attackers to access user or admin accounts. The Provisioning Manager applies improper authentication mechanisms to account-access requests; Mitel has not disclosed the specific faulty check or request field. No credentials or user interaction are required, and the resulting access can carry user or administrative privileges, but the advisory does not report direct code execution.
