| スコープ | 影響 | 可能性 |
|---|---|---|
| Other | Varies by Context 注記：If the product assumes that each resource has a unique identifier, the product could operate on the wrong resource if attackers can cause multiple resources to be associated with the same identifier. | |
| Access Control | Bypass Protection Mechanism 注記：If unique identifiers are assumed when protecting sensitive resources, then duplicate identifiers might allow attackers to bypass the protection. | |

潜在的な緩和策
Phases : Architecture and DesignWhere possible, use unique identifiers. If non-unique identifiers are detected, then do not operate any resource with a non-unique identifier and report the error appropriately.
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 weakness is probably closely associated with other issues related to doubling, such as CWE-675 (Duplicate Operations on Resource). It's often a case of an API contract violation (CWE-227).登録情報
