In Arista's MOS (Metamako Operating System) software which is supported on the 7130 product line, user enable passwords set in clear text could result in unprivileged users getting complete access to the systems. This issue affects: Arista Metamako Operating System MOS-0.13 and post releases in the MOS-0.1x train MOS-0.26.6 and prior releases in the MOS-0.2x train MOS-0.31.1 and prior releases in the MOS-0.3x train
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.7, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited data confidentiality, integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from arista, from arista 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 arista'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.
