CWE-267: Privilege Defined With Unsafe Actions
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.
常见后果
影响范围: Access Control
技术影响: Gain Privileges or Assume Identity
说明: A user can access restricted functionality and/or sensitive information that may include administrative functionality and user accounts.
潜在缓解措施
阶段: Architecture and Design Operation
描述: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
阶段: Architecture and Design Operation
策略: Environment Hardening
描述: 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.
