Vulnerability from variot - Updated: 2022-05-04 09:17

HollySys, founded in 1993, is a provider of automation and information technology solutions.

Hollysys' K-series main controller module K-CU01 has multiple denial of service vulnerabilities.

(1) Distort the ulMessageSize field in the UdpComHeader structure and send a malformed packet.

(2) Continuously sending data packets to the controller will cause the controller to deny service and cause the controller not to respond to normal requests.
