CWE-921 在没有访问控制机制中存储敏感数据

Storage of Sensitive Data in a Mechanism without Access Control

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

The software stores sensitive information in a file system or device that does not have built-in access control.

扩展描述

While many modern file systems or devices utilize some form of access control in order to restrict access to data, not all storage mechanisms have this capability. For example, memory cards, floppy disks, CDs, and USB devices are typically made accessible to any user within the system. This can become a problem when sensitive data is stored in these mechanisms in a multi-user environment, because anybody on the system can read or write this data.

On Android devices, external storage is typically globally readable and writable by other applications on the device. External storage may also be easily accessible through the mobile device's USB connection or physically accessible through the device's memory card port.
