Arista Networks — Vulnerabilities & Security Advisories 83

Browse all 83 CVE security advisories affecting Arista Networks. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Arista Networks specializes in high-performance data center switching and cloud networking solutions, primarily serving enterprise and service provider infrastructure. With sixty-four recorded Common Vulnerabilities and Exposures (CVEs), the company’s historical attack surface has predominantly featured remote code execution, cross-site scripting, and privilege escalation flaws within its management interfaces and network operating systems. These vulnerabilities often stem from input validation errors or improper access controls in legacy software versions, allowing attackers to gain unauthorized administrative access or disrupt network services. While Arista maintains a robust security posture through regular firmware updates and secure boot mechanisms, past incidents highlight the risks associated with complex network management platforms. The company actively addresses these issues via security advisories, emphasizing the importance of timely patching for deployed infrastructure to mitigate potential exploitation by malicious actors targeting critical network backbone components.
