WCF Misconfiguration: Metadata
Abstract
元数据可帮助攻击者了解系统和制定攻击计划。
Explanation
WCF 服务可配置为显示元数据。元数据会提供详细的服务描述信息，不应在生产环境中广播。
示例 1：以下代码会指示 WCF 广播服务的元数据。
ServiceMetaData 类的 HttpGetEnabled / HttpsGetEnabled 属性可定义服务是否会显示元数据。示例 1：以下代码会指示 WCF 广播服务的元数据。
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.HttpGetUrl = new Uri(EndPointAddress);
Host.Description.Behaviors.Add(smb);
