CVE-2024-38396

Estado: AnalizadaCrítica (9.8)—💥 PoC

Se descubrió un problema en iTerm2 3.5.x anterior a 3.5.2. El uso sin filtrar de una secuencia de escape para informar el título de una ventana, en combinación con la función de integración tmux incorporada (habilitada de forma predeterminada), permite a un atacante inyectar código arbitrario en la terminal, una vulnerabilidad diferente a CVE-2024-38395.

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.
