Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the heap-based buffer overflow vulnerability in RRAS through timely identification, testing, and application of vendor patches.
Implements memory protections such as ASLR and DEP that prevent arbitrary code execution from heap buffer overflows in RRAS.
Enforces boundary protections to monitor and control network communications, limiting remote attacker access to the vulnerable RRAS service.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap buffer overflow enables remote arbitrary code execution in exposed RRAS service without authentication.
NVD Description
Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.
Deeper analysisAI
