An internal security review has identified an unauthenticated remote code execution vulnerability in Cloud Networking Operating System (CNOS)’ optional REST API management interface. This interface is disabled by default and not vulnerable unless enabled. When enabled, it is only vulnerable where attached to a VRF and as allowed by defined ACLs. Lenovo strongly recommends upgrading to a non-vulnerable CNOS release. Where not possible, Lenovo recommends disabling the REST API management interface or restricting access to the management VRF and further limiting access to authorized management stations via ACL.
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 10 products from lenovo, from lenovo, from lenovo and 7 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2020, 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 lenovo'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.
