Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the Provisioning Manager component of Mitel MiVoice MX-ONE 7.3 (7.3.0.0.50) through 7.8 SP1 (7.8.1.0.14) could allow an unauthenticated attacker to conduct an authentication bypass attack due to improper authentication mechanisms. A successful exploit could allow an attacker to gain unauthorized access to user or admin accounts in the system.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
