Certain NETGEAR devices are affected by a buffer overflow by an unauthenticated attacker. This affects D8500 before 1.0.3.58, R6250 before 1.0.4.48, R7000 before 1.0.11.116, R7100LG before 1.0.0.64, R7900 before 1.0.4.38, R8300 before 1.0.2.144, R8500 before 1.0.2.144, XR300 before 1.0.3.68, R7000P before 1.3.2.132, and R6900P before 1.3.2.132.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.6, indicating it requires adjacent network access with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 20 products from netgear, from netgear, from netgear and 17 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For netgear's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
