Critical flaws let hackers hijack Daktronics billboards

CRITICAL vulnerabilities have been discovered in Daktronics controllers, impacting highway signs and digital billboards. A cybersecurity researcher identified three key issues: a path traversal exploit, an authenticated file upload vulnerability, and the use of default admin credentials. These flaws could allow unauthenticated users complete system control, enabling potential tampering with displayed content. Daktronics has issued patches and recommended users change default passwords. While the company quickly addressed the vulnerabilities, it is ultimately up to users to secure their devices from internet exposure.
