CVE-2024-35285Network attack vector

Unauthenticated command execution via unsanitized parameters

Published Oct 21, 2024 · Updated Oct 22, 2024

Command injection in NuPoint Unified Messaging in Mitel MiCollab 9.8.0.33 and earlier allows remote attackers to execute system commands. NuPoint accepts attacker-controlled parameters without sufficient sanitization before invoking a system command; Mitel has not disclosed the endpoint or parameter. No authentication or user interaction is required, and successful exploitation executes arbitrary commands in the system context, affecting data and service availability.
