Description

Impact

認証が不十分なため、トークン生成時に明示的に権限を付与しなくても管理人とモデレーターの発行した（もしくはMiAuth経由で生成された）APIトークンを利用した外部アプリが管理用のapiを呼び出せます。これにより、悪意のあるサードパーティアプリによるサーバー設定の更新などの操作や、オブジェクトストレージやメールサーバーのクレデンシャルの漏洩が発生します。

Workarounds

信頼できない外部アプリに対していかなるAPIトークンも発行しない

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
