WCF Misconfiguration: MSMQ Anonymous Transport Client

ABSTRACT

由于程序在連接 MSMQ 隊列時未能啟用 authentication，因此攻擊者可以將消息匿名提交至處理隊列。

EXPLANATION

如果連接用于將消息傳遞給其他程序的 MSMQ 隊列時未使用 authentication，攻擊者就可以提交惡意的匿名消息。

例 1：以下 WCF 配置文件中的 <netMsmqBinding/> 元素指示 WCF 在連接用于傳遞消息的 MSMQ 隊列時禁用 authentication。

<bindings>
<netMsmqBinding>
<binding>
<security>
<transport msmqAuthenticationMode="None" />
</security>
</binding>
</netMsmqBinding>
</bindings>
