CVE-2019-4640Network attack vector

Privileged code execution via unverified updates

Published Feb 19, 2020 · Updated Sep 17, 2024

Improper update verification in IBM Security Secret Server 10.7 allows remote authenticated users to execute malicious code. The patch, image-backup, and update processor accepts executable content without adequately establishing its origin or integrity before processing it. Exploitation requires high-privilege access and high attack complexity; successful execution can alter the server, with no disclosed data-reading or service-interruption impact.
