## Schwachstellen-Klasse

- **CWE-267** — Privilege Defined With Unsafe Actions
  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.
- **CWE-270** — Privilege Context Switching Error
  The product does not properly manage privileges while it is switching between different contexts that have different privileges or spheres of control.
- **CWE-648** — Incorrect Use of Privileged APIs
  The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.
- **CWE-78** — Improper Neutralization of Special Elements used in an OS Command (OS Command Injection)
  The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
