"value": "A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence."

"value": "Se encontr\u00f3 una falla de dise\u00f1o en la implementaci\u00f3n del control DirSync de Samba, que expone contrase\u00f1as y secretos en Active Directory a usuarios privilegiados y Controladores de Dominio de Solo Lectura (RODC). Esta falla permite a los RODC y a los usuarios que poseen el derecho GET_CHANGES acceder a todos los atributos, incluidos secretos y contrase\u00f1as confidenciales. Incluso en una configuraci\u00f3n predeterminada, las cuentas RODC DC, que solo deber\u00edan replicar algunas contrase\u00f1as, pueden obtener acceso a todos los secretos del dominio, incluido el vital krbtgt, eliminando efectivamente la distinci\u00f3n RODC/DC. Adem\u00e1s, la vulnerabilidad no tiene en cuenta las condiciones de error (fallo de apertura), como situaciones de falta de memoria, lo que potencialmente otorga acceso a atributos secretos, incluso bajo la influencia de un atacante con pocos privilegios."
