一般的な結果
| スコープ | 影響 | 可能性 |
|---|---|---|
| Authentication | Gain Privileges or Assume Identity 注記：If an authentication artifact is used across multiple applications or services, it allows an adversary who is able to compromise the authentication artifact to gain access to all applications or services that use that artifact. | |
| Availability | Other 注記：In order to revoke access to an adversary who has compromised a shared authentication artifact, that artifact must be invalidated which would affect the availability of any user who has legitimately obtained the artifact to authenticate. |
潜在的な緩和策
Phases : ImplementationEnforce re-authentication per user device. This prevents another user from obtaining the singular authentication artifact and making authenticated requests without authenticating.
Phases : Implementation
Use unique authentication artifacts per user device that will only be accepted if used on that device.
Phases : Implementation
Ensure that unique authentication artifacts are used for each application or service within an organization to prevent potential reuse across applications.
脆弱性マッピングノート
理由 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
ノート
This entry was created in CWE 5.0 to address known gaps in CWE coverage. It is not as complete as other new entries that were published in recent years. The CWE Team plans to work with the CWE community to make this entry more complete in later 5.x releases.参考文献
