CVE-2023-32562

Remote code execution via unrestricted file upload

Published Aug 10, 2023 · Updated Mar 6, 2025

Unrestricted file upload in Ivanti Avalanche 6.3.x and earlier allows remote authenticated users to execute arbitrary code. The upload handler accepts dangerous file types without restriction, but Ivanti has not published the affected endpoint or its validation logic. High privileges and adjacent-network access are required; successful exploitation runs attacker-controlled code on the server.
