HiOS Switch Platform versions 09.1.00 through 09.4.04 and 10.0.00 through 10.3.00 contain a denial-of-service vulnerability in the web interface that allows remote attackers to reboot the affected device by sending a malicious HTTP GET request to a specific endpoint. Attackers can trigger an uncontrolled reboot condition through crafted HTTP requests to cause service disruption and unavailability of the switch.
