Com 3.204 CVEs catalogadas e 53 confirmadas em exploração ativa pelo CISA KEV, a taxa de exploração dos produtos Cisco está 3,7 vezes acima da média geral do catálogo, o que indica risco operacional significativamente elevado para organizações que dependem dessas tecnologias. Há ainda 199 vulnerabilidades de severidade crítica e 77 com prova de conceito pública disponível, ampliando a superfície de ataque explorável sem necessidade de capacidade ofensiva avançada. O tipo de falha mais recorrente é CWE-20 (validação de entrada inadequada), uma classe de vulnerabilidade frequentemente presente em componentes de rede e que tende a produzir impacto amplo quando explorada. A CVE mais perigosa em exploração ativa neste momento é CVE-2021-1498, com EPSS máximo de 1,0 — indicando probabilidade de exploração extremamente alta —, e deve ser tratada como prioridade imediata em qualquer processo de gestão de patches.
