Blink routers BL-WR9000 V2.4.9, BL-AC1900 V1.0.2, BL-AC2100_AZ3 V1.0.4, BL-X10_AC8 V1.0.5, BL-LTE300 V1.2.3, BL-F1200_AT1 V1.0.0, BL-X26_AC8 V1.2.8, BLAC450M_AE4 V4.0.0 and BL-X26_DA3 V1.2.7 were discovered to contain a command injection vulnerability via the routepwd parameter in the sub_45B238 function.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.8, indicating it can be exploited remotely over the network 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 18 products from b-link, from b-link, from b-link and 15 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2025, 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 b-link'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.
