CWE-284 访问控制不恰当

Improper Access Control

结构: Simple

Abstraction: Class

状态: Incomplete

被利用可能性: unkown

基本描述

The software does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

扩展描述

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the software by gaining privileges, reading sensitive information, executing commands, evading detection, etc.

There are two distinct behaviors that can introduce access control weaknesses:

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-46 Architecture and Design

策略: Separation of Privilege

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
Ensure that appropriate compartmentalization is built into the system design and that the compartmentalization serves to allow for and further reinforce privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide when it is appropriate to use and to drop system privileges.
