CVE-2026-31928Network attack vector

Full system access via unchanged default web credentials

Published Jun 26, 2026 · Updated Jun 26, 2026

Hard-coded credentials in Daktronics DMP-5000, DMP-8000, and VFC-DMP-5000 firmware allow remote attackers to gain full system access. The administrative web account ships with weak default credentials, and initialization and normal operation do not require those credentials to be replaced. Network access to the web interface and unchanged default credentials are sufficient for administrative control of device data and configuration.
