CVE-2026-34406

Estado: AnalizadaCrítica (9.4)—

APTRS (Automated Penetration Testing Reporting System) is a Python and Django-based automated reporting tool designed for penetration testers and security organizations. Prior to version 2.0.1, the edit_user endpoint (POST /api/auth/edituser/<pk>) allows Any user who can reach that endpoint and submit crafted permission to escalate their own account (or any other account) to superuser by including "is_superuser": true in the request body.

Leer descripción completaMostrar menos

The root cause is that CustomUserSerializer explicitly includes is_superuser in its fields list but omits it from read_only_fields, making it a writable field. The edit_user view performs no additional validation to prevent non-superusers from modifying this field. Once is_superuser is set to true, gaining unrestricted access to all application functionality without requiring re-authentication. This issue has been patched in version 2.0.1.

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.

AV:N/PR:L permite escalada remota con privilegios: usuario autenticado modifica is_superuser en endpoint /api/auth/edituser, ganando acceso administrativo sin re-autenticación (CWE-915 insuficiente validación).

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 causa raíz es que CustomUserSerializer incluye explícitamente is_superuser en su lista de campos pero lo omite de read_only_fields, convirtiéndolo en un campo editable. La vista edit_user no realiza ninguna validación adicional para evitar que los no-superusuarios modifiquen este campo. Una vez que is_superuser se establece en true, se obtiene acceso sin restricciones a toda la funcionalidad de la aplicación sin requerir re-autenticación. Este problema ha sido parcheado en la versión 2.0.1."
