3) Resource management error (CVE-ID: CVE-2022-2048)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when handling invalid HTTP/2 requests. A remote attacker can send specially crafted requests to the server and perform a denial of service (DoS) attack.
