FKIE_CVE-2020-25720

Vulnerability from fkie_nvd - Published: 2024-11-17 11:15 - Updated: 2024-11-18 17:11
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
A vulnerability was found in Samba where a delegated administrator with permission to create objects in Active Directory can write to all attributes of the newly created object, including security-sensitive attributes, even after the object's creation. This issue occurs because the administrator owns the object due to the lack of an Access Control List (ACL) at the time of creation and later being recognized as the 'creator owner.' The retained significant rights of the delegated administrator may not be well understood, potentially leading to unintended privilege escalation or security risks.

Este problema se produce porque el administrador es el propietario del objeto debido a la falta de una lista de control de acceso (ACL) en el momento de la creaci\u00f3n y, posteriormente, se lo reconoce como el \"propietario creador\". Es posible que no se comprendan bien los derechos importantes que conserva el administrador delegado, lo que puede provocar una escalada de privilegios no deseada o riesgos de seguridad."
