CWE-651: Exposure of WSDL File Containing Sensitive Information
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
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).
常见后果
影响范围: Confidentiality
技术影响: Read Application Data
说明: The attacker may find sensitive information located in the WSDL file.
潜在缓解措施
阶段: Architecture and Design
描述: 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.
阶段: Architecture and Design
策略: Separation of Privilege
描述: 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.
阶段: Architecture and Design
描述: Do not use method names in WSDL that might help an adversary guess names of private methods/resources used by the service.
