Análise Vexday

Apache Tomcat acumula 131 CVEs catalogadas, das quais 5 estão confirmadas em exploração ativa pelo CISA KEV — representando uma taxa 8,5 vezes acima da média geral do catálogo, sinal claro de que vulnerabilidades nessa tecnologia atraem atenção consistente de agentes maliciosos. O tipo de falha mais recorrente é CWE-20 (validação de entrada imprópria), que historicamente viabiliza desde execução remota de código até desvios de controle de acesso. A CVE mais crítica atualmente ativa, CVE-2017-12617, apresenta EPSS de 0,9999 — praticamente a pontuação máxima de probabilidade de exploração —, exigindo atenção prioritária em qualquer ambiente que ainda execute versões vulneráveis. Os 17 novos registros surgidos nos últimos 90 dias, somados às 19 CVEs de severidade crítica, indicam uma superfície de ataque que segue crescendo e que demanda ciclos de patching frequentes e monitoramento contínuo.
