Flex Misconfiguration: Debug Information

ABSTRACT

調試信息可幫助攻擊者了解系統并規劃攻擊方式。

EXPLANATION

如果您使用 Blaze DS 來記錄所有意外事件，services-config.xml 描述符文件將指定一個 "Logging" XML 元素來描述記錄的各個方面。如下所示：

例：

<logging>
<target class="flex.messaging.log.ConsoleTarget" level="Debug">
<properties>
<prefix>[BlazeDS]</prefix>
<includeDate>false</includeDate>
<includeTime>false</includeTime>
<includeLevel>false</includeLevel>
<includeCategory>false</includeCategory>
</properties>
<filters>
<pattern>Endpoint.*</pattern>
<pattern>Service.*</pattern>
<pattern>Configuration</pattern>
</filters>
</target>
</logging>

此 target 標簽具有一個名為 level 的屬性，為可選項，用來指明日志級別。如果調試級別被設置得過于詳細，您的應用程序可能會向日志文件寫入敏感數據。
