CVE-2024-35287

Elevated command execution via overprivileged resource

Published Oct 21, 2024 · Updated Oct 22, 2024

Local privilege escalation in Mitel MiCollab 9.8 SP1 (9.8.1.5) and earlier allows local users to execute commands with elevated privileges. The NuPoint Messenger component executes a resource with permissions beyond those it requires; Mitel has not identified the resource or disclosed the triggering operation. Local administrative access is required, and successful exploitation grants arbitrary command execution with elevated privileges across the system.
