Microsoft rolled out updates to plug some security holes in its Windows operating systems and other software. A major concern for enterprises is a critical bug in the DNS service on Windows Server 2008 through 2019 that can be used to remotely install software of the attacker’s choice. CVE-2021-24078 earned a CVSS score of 9.8, which is as risky as they come.
This vulnerability can be exploited remotely by getting a vulnerable DNS server to query for a domain it has not come across before. For example, sending a phishing email with a link to a new domain or images embedded that call out to a new domain.
CVE-2021-24078 could let a cyber attacker steal lots of data by changing the destination for the web traffic of an organization. For instance, pointing internal appliances or outlook email access at a malicious server.
