DescriptionCVE.org

Integer overflow or wraparound in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.

Executive ViewAI

Why It Matters

A critical vulnerability in Windows RRAS enables remote code execution without authentication, potentially allowing attackers to compromise internal network infrastructure and gain unauthorized access to sensitive systems. Organizations running RRAS services face immediate risk of breach, lateral movement, and data exfiltration until mitigation measures are implemented.

Business Impact: Severe
Compensating Controls

Disable RRAS if not actively required; restrict inbound access via firewall to authorized IP ranges only; implement network segmentation isolating RRAS servers from critical assets; deploy endpoint detection and response (EDR) on RRAS servers; enable NetFlow/packet capture for anomaly detection; require multi-factor authentication for any remote access; disable unused authentication protocols; monitor for suspicious process execution and network connections on RRAS systems.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Heap Overflow HIGH

A heap overflow occurs when a program writes data beyond the bounds of a buffer allocated in the heap memory region.
