Arista Networks, Inc.

Arista Networks operates a broadly represented portfolio of network switching, routing, and security appliances that occupy critical infrastructure roles in enterprise and cloud deployments, creating a substantial attack surface across the datacenter and edge. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a moderate tendency toward public exploit availability; the exposure concentrates in flagship products such as EOS, the NG Firewall, and the 7500 series switches. Recurring weakness classes include improper authentication, OS command injection, and improper access control—flaws typical of complex network operating systems that expose command interfaces and privilege-boundary logic. Defenders should track this vendor's advisories closely given the critical role its devices play in network segmentation and access control, and prioritize remediation for internet-facing or untrusted-input-adjacent deployments. Current exploitation activity and exposure counts are shown alongside this summary.
