處理weblogic、tomcat關閉不安全的http請求

導讀	不安全的HTTP方法一般包括：TRACE、PUT、DELETE、COPY 等。其中最常見的為TRACE方法可以回顯伺服器收到的請求，主要用於測試或診斷，惡意攻擊者可以利用該方法進行跨站跟蹤攻擊（即XST攻擊），從而進行網站釣魚、盜取管理員cookie等。

禁止不安全的http請求方式PUT、DELETE、HEAD、OPTIONS、TRACE等，只保留GET和POST請求。其中tomcat和weblogic部署解決方案都是在web.xml中新增配置檔案，但格式有所差異，詳情如下：

1）Tomcat：在web.xml中新增：

<security-constraint>
<web-resource-collection>
<url-pattern>/*</url-pattern>
<http-method>PUT</http-method>
<http-method>DELETE</http-method>
<http-method>HEAD</http-method>
<http-method>OPTIONS</http-method>
<http-method>TRACE</http-method>
<http-method>PATCH</http-method>
<http-method>COPY</http-method>
<http-method>LINK</http-method>
<http-method>UNLINK</http-method>
<http-method>PURGE</http-method>
<http-method>LOCK</http-method>
<http-method>UNLOCK</http-method>
<http-method>PROPFIND</http-method>
<http-method>VIEW</http-method>
</web-resource-collection>
<auth-constraint>
</auth-constraint>
</security-constraint>

2）Weblogic:在web.xml中新增：

<security-constraint>
<web-resource-collection>
<web-resource-name>sgpssc</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>PUT</http-method>
<http-method>DELETE</http-method>
<http-method>HEAD</http-method>
<http-method>OPTIONS</http-method>
<http-method>TRACE</http-method>
<http-method>PATCH</http-method>
<http-method>COPY</http-method>
<http-method>LINK</http-method>
<http-method>UNLINK</http-method>
<http-method>PURGE</http-method>
<http-method>LOCK</http-method>
<http-method>UNLOCK</http-method>
<http-method>PROPFIND</http-method>
<http-method>VIEW</http-method>
</web-resource-collection>
<auth-constraint/>
</security-constraint>

可以透過谷歌瀏覽器的外掛Postman工具檢測，是否修復。
