CVE-2018-4901

Estado: ModificadaAlta (8.8)—💥 PoC

Se ha descubierto un problema en Adobe Acrobat Reader 2018.009.20050 y anteriores, 2017.011.30070 y anteriores y 2015.006.30394 y anteriores. La vulnerabilidad se debe a un cálculo que escribe datos más allá del final del búfer planeado; el cálculo forma parte de la representación de identidad del documento. Un atacante podría aprovechar la vulnerabilidad para corromper datos sensibles o ejecutar código arbitrario.

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.
