名前: Improper Control of Document Type Definition
The product does not restrict a reference to a Document Type Definition (DTD) to the intended control sphere. This might allow attackers to reference arbitrary DTDs, possibly causing the product to expose files, consume excessive system resources, or execute arbitrary http requests on behalf of the attacker.

| スコープ | 影響 | 可能性 |
|---|---|---|
| Confidentiality | Read Files or Directories 注記：If the attacker is able to include a crafted DTD and a default entity resolver is enabled, the attacker may be able to access arbitrary files on the system. | |
| Availability | DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory) 注記：The DTD may cause the parser to consume excessive CPU cycles or memory using techniques such as nested or recursive entity references (CWE-776). | |
| Integrity Confidentiality Availability Access Control | Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity 注記：The DTD may include arbitrary HTTP requests that the server may execute. This could lead to other attacks leveraging the server's trust relationship with other entities. |

脆弱性マッピングノート
理由 : This CWE entry is at the Variant 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.
