An inconsistency in Kibana's file access authorization logic allows a low-privileged authenticated user to retrieve, modify, and delete case attachments that belong to feature areas they are not authorized to access. Because the access control check and the resource retrieval use different resolution mechanisms, an authenticated attacker with limited file management permissions can obtain the contents of, modify, or delete protected case attachments \u2014 such as those associated with Security Solution cases \u2014 without holding the privileges required to access those features."}, {"lang": "es", "value": "Elusi\u00f3n de autorizaci\u00f3n mediante clave controlada por el usuario (CWE-639) en Kibana puede conducir a la revelaci\u00f3n de informaci\u00f3n no autorizada y al compromiso de la integridad de los adjuntos de casos a trav\u00e9s de Abuso de Privilegios (CAPEC-122).
