CVE-2023-39293Network attack vector

Authenticated command execution via unsanitized Controller Manager parameters

Published Aug 14, 2023 · Updated Oct 9, 2024

Command injection in Mitel MiVoice Office 400 SMB Controller 1.2.5.23 and earlier allows remote authenticated users to execute system commands. Controller Manager insufficiently sanitizes attacker-controlled parameters before using them in a system-command context. Access to the Controller Manager interface with high privileges is required; successful exploitation compromises system data and availability.
