CVE-2020-11076

Estado: ModificadaAlta (7.5)—💥 PoC

En Puma (RubyGem) versiones anteriores a 4.3.4 y 3.12.5, un atacante podría hacer pasar sin autorización una respuesta HTTP, mediante el uso de un encabezado de codificación transfer no válido. El problema ha sido corregido en Puma versión 3.12.5 y Puma versión 4.3.4.

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.
