CVE-2019-5825

Estado: AnalizadaMedia (6.5)⚠ Explotación activa💥 Exploit

Una escritura fuera de límites en JavaScript en Google Chrome versiones anteriores a 73.0.3683.86, permitió a un atacante remoto, explotar potencialmente una corrupción de la pila por medio de una página HTML diseñada.

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).

CISA KEV — explotada activamente

💥 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.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N/UI:R indica explotación remota con interacción del usuario (página HTML crafted). CWE-787 (out of bounds write) en JavaScript causa corrupción de heap → DoS. Vulnerabilidad explotada activamente.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
