CVE-2025-34064

A cloud infrastructure misconfiguration in OneLogin AD Connector results in log data being sent to a hardcoded S3 bucket (onelogin-adc-logs-production) without validating bucket ownership. An attacker who registers this unclaimed bucket can begin receiving log files from other OneLogin tenants. These logs may contain sensitive data such as directory tokens, user metadata, and environment configuration. This enables cross-tenant leakage of secrets, potentially allowing JWT signing key recovery and user impersonation.

Summary		(es) Una configuración incorrecta de la infraestructura en la nube en OneLogin AD Connector provoca el envío de datos de registro a un bucket S3 codificado (onelogin-adc-logs-production) sin validar su propiedad. Un atacante que registre este bucket no reclamado puede empezar a recibir archivos de registro de otros inquilinos de OneLogin. Estos registros pueden contener datos confidenciales, como tokens de directorio, metadatos de usuario y configuración del entorno. Esto facilita la filtración de secretos entre inquilinos, lo que podría permitir la recuperación de claves de firma JWT y la suplantación de identidad de usuarios.
