CVE-2025-23114

Root code execution via unvalidated TLS certificates

Published Feb 5, 2025 · Updated Mar 13, 2025

Improper certificate validation in Veeam Updater allows man-in-the-middle attackers to execute arbitrary code on affected backup appliances. The component accepts an untrusted TLS certificate while retrieving updates, allowing intercepted traffic to substitute attacker-controlled update content. An attacker must control the update network path; successful code execution runs with root-level permissions on the appliance server.
