Vexday analysis

O portfólio de vulnerabilidades da Arista Networks soma 80 CVEs catalogadas, das quais 8 são de severidade crítica e 1 está confirmada em exploração ativa no catálogo KEV da CISA — proporção que coloca o vendor ACIMA da média geral do catálogo em 2,8 vezes, sinalizando atenção redobrada mesmo diante de um volume total relativamente contido. O tipo de falha mais recorrente é CWE-284 (controle de acesso impróprio), padrão que tende a favorecer movimentação lateral e escalada de privilégios em ambientes de rede. A CVE mais perigosa atualmente ativa é CVE-2026-7473, ainda com EPSS de 0,0084, indicando probabilidade de exploração em massa relativamente baixa no curto prazo, mas cuja presença no KEV exige tratamento prioritário. O surgimento de 16 novas CVEs nos últimos 90 dias reforça a necessidade de ciclos de patching contínuos para os operadores desses equipamentos.
