CVE-2020-29599

Estado: ModificadaAlta (7.8)—💥 PoC

ImageMagick versiones anteriores a 6.9.11-40 y versiones 7.x anteriores a 7.0.10-40 maneja inapropiadamente la opción -authenticate, que permite establecer una contraseña para archivos PDF protegidos con contraseña. La contraseña controlada por el usuario no era escapada y saneada apropiadamente y, por lo tanto, fue posible inyectar comandos de shell adicionales por medio del archivo coders/pdf.c

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.
