Esta vulnerabilidad se debe a un enmascaramiento insuficiente de la información confidencial antes de que se escriba en los archivos de registro del sistema. Un atacante podría explotar esta vulnerabilidad accediendo a los registros de un sistema afectado. Una explotación exitosa podría permitirle acceder a información confidencial que debería estar restringida."
