Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates CVE-2025-21410 by requiring timely remediation through application of Microsoft patches for the RRAS flaw.
Prevents remote exploitation of the RRAS vulnerability by enforcing boundary protections that block unauthorized network access to vulnerable service ports.
Reduces attack surface by configuring systems to disable unnecessary RRAS functionality, eliminating exposure to the remote code execution vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
RCE vulnerability in network-accessible RRAS service enables T1190 (Exploit Public-Facing Application) for initial remote exploitation and T1059 (Command and Scripting Interpreter) for arbitrary code execution on the target.
