Stack Buffer Overflow in BUFFALO Wi-Fi HTTP Request Handler

CVE-2026-95104 is a stack-based buffer overflow vulnerability (CWE-121) affecting BUFFALO Wi-Fi products that can be exploited through unauthenticated HTTP requests. This vulnerability matters because it requires no authentication to trigger, meaning any attacker with network access to the affected device can craft a malicious HTTP request to cause a denial-of-service condition. BUFFALO Wi-Fi routers and access points are commonly deployed in enterprise networks, small offices, and home environments, making this a broad exposure issue for organizations relying on these devices for network connectivity and security perimeter defense.

While this specific CVE lacks direct MITRE ATT&CK mappings, Casky's Claude-powered analysis engine would identify the underlying attack patterns associated with network service exploitation and DoS delivery mechanisms. A practitioner using Casky would see detection insights across skills related to CWE-121 exploitation patterns, HTTP protocol abuse, and unauthenticated service attacks. The extended reasoning capabilities would flag this as fitting techniques like T1190 (Exploit Public-Facing Application) and T1499 (Endpoint Denial of Service), helping security teams understand how this vulnerability chains into broader attack frameworks and what defensive monitoring—such as HTTP request anomaly detection and resource exhaustion thresholds—should be prioritized for BUFFALO device protection.
