CVSS v3.1

Official Description

A vulnerability in Mitel 6900 Series IP (MiNet) phones excluding 6970, versions 1.8 (1.8.0.12) and earlier, could allow a unauthenticated attacker with physical access to the phone to gain root access due to insufficient access control for test functionality during system startup. A successful exploit could allow access to sensitive information and code execution.

Technical Analysis

CVE-2022-29854 requires local access, meaning attackers must already have a foothold on the target system.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 6.8.
