At SpinetiX we inspire businesses to unlock the potential of their story. We believe in the power of digital signage as a dynamic new storytelling platform to engage with people. For more than 13 years, we have been constantly innovating to deliver cutting-edge digital signage solutions that help our customers shine. Fusion is a built-in content management application accessible from a standard web browser - it is pre-installed on every HMP200, HMP130, and HMP100 device, and does not require any additional license, cost, or software installation.
The application interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site.
