The flaws include an unauthenticated path traversal, an authenticated arbitrary file upload, and default administrator credentials that grant full root-level access. Security researcher Thomas Jou found multiple internet-exposed controllers exploitable remotely. Successful exploitation could allow attackers to tamper with public signage content, display false roadway alerts, or fully compromise devices. Daktronics has released patched firmware. Recommended actions include applying firmware updates, removing internet exposure, changing default credentials, and monitoring for unauthorized content changes. ## Full article daily.dev links to this article rather than hosting it.
