CVE-2023-41991

Estado: AnalizadaMedia (5.5)⚠ Explotación activa💥 PoC

Se solucionó un problema de validación de certificados. Este problema se solucionó en macOS Ventura 13.6, iOS 16.7 y iPadOS 16.7. Es posible que una aplicación maliciosa pueda eludir la validación de firmas. Apple tiene conocimiento de un informe que indica que este problema puede haber sido explotado activamente en versiones de iOS anteriores a iOS 16.7.

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.

Explotación corregida por reglas (vector CVSS): era T1068

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.
