| CVE-2021-24078 | Windows DNS Server Remote Code Execution Vulnerability | Windows Server 2019 | Critical | 11-02-2021 |
Technical Information
Brief overview of the risk:
This vulnerability exists in Windows Domain Name System (DNS) servers when it fails to properly handle requests. To exploit this vulnerability a remote attacker has to send a DNS query to the DNS server for a domain it has never seen so that the server requests the root DNS server. The attacker then has to spoof the response to the DNS server before the root DNS sends the actual response. This bug can be exploited by a remote attacker without any user interactions or a privileged account. An attacker who successfully exploited the vulnerability could execute arbitrary code in the context of the logged on user. This vulnerability is exploitable only if the server is configured to be a DNS server.
