Microhard Systems 3G/4G Cellular Ethernet and Serial Gateway systems allow 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. Many versions are affected.
