Com 8 CVEs confirmadas em exploração ativa pelo CISA KEV em um universo de 162 catalogadas, a taxa de exploração da Zyxel é 11 vezes superior à média geral do catálogo, o que indica que os dispositivos dessa fabricante atraem interesse concreto de agentes maliciosos, não apenas teórico. O tipo de falha mais recorrente é CWE-78 (injeção de comandos no sistema operacional), categoria que permite execução arbitrária de comandos e costuma resultar em comprometimento total do equipamento. A CVE mais crítica ativa no momento, CVE-2022-30525, registra EPSS de 0,9994 — probabilidade de exploração próxima ao máximo da escala —, sinalizando risco iminente para ambientes que ainda não aplicaram a correção correspondente. Os 23 itens de severidade crítica e as 11 CVEs surgidas nos últimos 90 dias reforçam a necessidade de ciclos de patching contínuos e prioritários para qualquer organização que opere equipamentos Zyxel.
