CWE-271—Privilege Dropping / Lowering Errors

名称

Privilege Dropping / Lowering Errors

描述

The product does not drop privileges before passing control of a resource to an actor that does not have those privileges.

In some contexts, a system executing with elevated permissions will hand off a process/file/etc. to another process or user. If the privileges of an entity are not reduced, then elevated privileges are spread throughout a system and possibly to an attacker.

常见后果

范围：

Access Control

影响：

Gain Privileges or Assume Identity

注释：

If privileges are not dropped, neither are access rights of the user. Often these rights can be prevented from being dropped.

范围：

Access Control, Non-Repudiation

影响：

Gain Privileges or Assume Identity, Hide Activities

注释：

If privileges are not dropped, in some cases the system may record actions as the user which is being impersonated rather than the impersonator.
