Microsoft DNS Server Unauthenticated RCE | MSSP Advisory

Microsoft patched 138 vulnerabilities this month with 30 rated Critical, including remote code execution flaws in DNS Server and Netlogon services. The DNS Server vulnerability allows unauthenticated remote code execution while the Netlogon flaw enables authenticated RCE on domain controllers. Both vulnerabilities affect core Windows Server infrastructure that most environments depend on for basic network operations.

Your RMM agents communicate through DNS resolution and your clients run Windows domain controllers with Netlogon for authentication, making these Critical-rated RCE vulnerabilities direct attack vectors into both your infrastructure and every client network. Missing these patches means attackers can compromise domain controllers and DNS servers that your remote management tools rely on to reach client systems.
