Command injection vulnerability in Linksys MR8300 router while Registration to DDNS Service. By specifying username and password, an attacker connected to the router's web interface can execute arbitrary OS commands. The username and password fields are not sanitized correctly and are used as URL construction arguments, allowing URL redirection to an arbitrary server, downloading an arbitrary script file, and eventually executing the file in the device. This issue affects: Linksys MR8300 Router 1.0.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.2, requiring local system access to exploit with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from linksys, from linksys organizations running these solutions should prioritize assessment and patching.
Reported in 2022, 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 linksys'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.
