New Controller Flaws Expose Highway Signs to Hacking

Vulnerabilities Put Public Displays at Risk

US authorities have warned of three vulnerabilities in Daktronics controllers used in highway signs and billboards. The Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory after a researcher discovered the flaws. The vulnerabilities affect some Daktronics controllers, potentially allowing hackers to access and control the devices.

The vulnerabilities include critical and high-severity flaws that could be exploited by hackers to gain remote access to the controllers. Daktronics controllers are used in various public display systems, including highway signs and billboards. If exploited, the vulnerabilities could allow hackers to display false information or disrupt the normal functioning of the signs.

Can Hackers Easily Exploit the Flaws?

The researcher who discovered the vulnerabilities found that the flaws could be exploited using relatively simple methods. The CISA advisory provides details on the vulnerabilities and recommends that organizations take immediate action to mitigate the risks. This includes applying patches and implementing other security measures to prevent potential attacks.

The exposure of these vulnerabilities highlights the potential risks associated with connected devices used in public infrastructure. As the use of connected devices continues to grow, it is likely that more vulnerabilities will be discovered, emphasizing the need for robust security measures.

What type of devices are affected by the vulnerabilities? The vulnerabilities affect some Daktronics controllers used in highway signs and billboards. Organizations using these devices should apply patches and implement other security measures.
