What is CVE-2021-33824?

A vulnerability has been identified in the Moxa Mgate MB3180 gateway that allows attackers to exploit the server by sending incomplete HTTP requests using tools such as slowhttptest. This leads to a situation where the server remains in a waiting state, consuming resources until they are exhausted, thereby causing a denial-of-service condition. Prolonged exploitation can severely hinder the gateway's functionality, affecting network operations.
