脆弱性 作成中
JA

ウェブサービス・アーキテクチャーは、一般にアクセス可能なサービスに関する情報と、これらのサービスの呼び出し元がそれらとどのように相互作用すべきか(例えば、どのようなパラメータを期待し、どのようなタイプを返すか)を含むウェブサービス定義言語(WSDL)ファイルを公開することを要求するかもしれない。

以下のいずれかに該当する場合、情報暴露が発生する可能性がある:

EN

The Web services architecture may require exposing a Web Service Definition Language (WSDL) file that contains information on the publicly accessible services and how callers of these services should interact with them (e.g. what parameters they expect and what types they return).

An information exposure may occur if any of the following apply:

Scope: Confidentiality / Impact: Read Application Data
Limit access to the WSDL file as much as possible. If services are provided only to a limited number of entities, it may be better to provide WSDL privately to each of these entities than to publish WSDL publicly.
Make sure that WSDL does not describe methods that should not be publicly accessible. Make sure to protect service methods that should not be publicly accessible with access controls.
Do not use method names in WSDL that might help an adversary guess names of private methods/resources used by the service.
