CVE-2025-5120

Estado: AnalizadaCrítica (10)—

A sandbox escape vulnerability was identified in huggingface/smolagents version 1.14.0, allowing attackers to bypass the restricted execution environment and achieve remote code execution (RCE). The vulnerability stems from the local_python_executor.py module, which inadequately restricts Python code execution despite employing static and dynamic checks. Attackers can exploit whitelisted modules and functions to execute arbitrary code, compromising the host system. This flaw undermines the core security boundary intended to isolate untrusted code, posing risks such as unauthorized code execution, data leakage, and potential integration-level compromise. The issue is resolved in version 1.17.0.

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).

🎯 Técnicas ATT&CK

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

Vulnerabilidad en aplicación web expuesta (AV:N, PR:N, UI:N) con escape de sandbox que permite ejecución de código arbitrario a través de módulos whitelisteados, afectando confidencialidad, integridad y disponibilidad.

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.

La vulnerabilidad se origina en el módulo local_python_executor.py, que restringe inadecuadamente la ejecución de código Python a pesar de emplear comprobaciones estáticas y dinámicas. Los atacantes pueden explotar módulos y funciones incluidos en la lista blanca para ejecutar código arbitrario, comprometiendo así el sistema host. Esta falla socava la seguridad básica diseñada para aislar el código no confiable, lo que plantea riesgos como la ejecución no autorizada de código, la fuga de datos y la posible vulneración de la integración. El problema se ha resuelto en la versión 1.17.0."
