CVE-2020-4464

Estado: ModificadaAlta (8.8)—💥 PoC

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 traditional could allow a remote attacker to execute arbitrary code on a system with a specially-crafted sequence of serialized objects over the SOAP connector. IBM X-Force ID: 181489.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
