CVE-2026-28442

Estado: AnalizadaAlta (8.5)—

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.2-beta3, users are restricted from deleting internal system files or folders through the application interface. However, when interacting directly with the API, these restrictions can be bypassed. By altering the path parameter in the delete request, internal OS files and directories can be removed successfully. The backend processes these manipulated requests without validating whether the targeted path belongs to restricted system locations. This demonstrates improper input validation and broken access control on sensitive filesystem operations. No known public patch is available.

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.

Acceso remoto con PR:L (requiere credencial válida) a API sin validación de entrada en rutas del sistema. Permite manipular/eliminar archivos críticos del SO y causar indisponibilidad.

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.

En la versión 1.5.2-beta3, los usuarios tienen restringido eliminar archivos o carpetas internos del sistema a través de la interfaz de la aplicación. Sin embargo, al interactuar directamente con la API, estas restricciones pueden ser eludidas. Al alterar el parámetro de ruta en la solicitud de eliminación, los archivos y directorios internos del sistema operativo pueden ser eliminados con éxito. El backend procesa estas solicitudes manipuladas sin validar si la ruta objetivo pertenece a ubicaciones restringidas del sistema. Esto demuestra una validación de entrada incorrecta y un control de acceso roto en operaciones sensibles del sistema de archivos. No hay ningún parche público conocido disponible."
