In Arista EOS malformed packets can be incorrectly forwarded across VLAN boundaries in one direction. This vulnerability is only susceptible to exploitation by unidirectional traffic (ex. UDP) and not bidirectional traffic (ex. TCP). This affects: EOS 7170 platforms version 4.21.4.1F and below releases in the 4.21.x train; EOS X-Series versions 4.21.11M and below releases in the 4.21.x train; 4.22.6M and below releases in the 4.22.x train; 4.23.4M and below releases in the 4.23.x train; 4.24.2.1F and below releases in the 4.24.x train.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.3, 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 limited integrity, for affected systems. Impacting 49 products from arista, from arista, from arista and 46 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 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.
