CVE-2024-35314Network attack vector

Script execution via unsanitized desktop-client parameters

Published Oct 21, 2024 · Updated Mar 25, 2025

Argument injection in the Mitel MiCollab desktop client allows remote attackers to execute arbitrary scripts through crafted parameters. The client insufficiently sanitizes attacker-controlled parameters, allowing injected arguments to alter script execution; Mitel has not disclosed the affected handler. Exploitation requires user interaction and affects MiCollab 9.7.1.110 and earlier and MiVB SVI 1.0.0.25.
