常见的影响
| 范围 | 影响 | 注释 |
|---|---|---|
| Access Control | Gain Privileges or Assume Identity | A user can assume the identity of another user with separate privileges in another context. This will give the user unauthorized access that may allow them to acquire the access information of other users. |
可能的缓解方案
MIT-1 ['Architecture and Design', 'Operation']
策略:
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
MIT-17 ['Architecture and Design', 'Operation']
策略: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
MIT-49 Architecture and Design
策略: Separation of Privilege
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
