Privacy Violation: Image

C#/VB.NET/ASP.NET

Abstract

对业务报告等敏感信息处理不当会危及到公司隐私，这是一种非法行为。

Explanation

当以未加密格式将敏感数据保存在磁盘上时，则会发生 privacy violation。

例 1：下列 ASPX 代码将通过 XML 数据源 SensitiveXMLData 生成敏感财务信息图表的 DataVisualization 控件实例化：


        <asp:Chart ID="Chart1" runat="server" ImageLocation="~/Temporary/Graph"
            ImageType="Jpeg" DataSourceID="SensitiveXMLData" ImageStorageMode="UseImageLocation">
            <series>
                .
                .
                .
            </series>
            <chartareas>
                <asp:ChartArea Name="ChartArea1">
                </asp:ChartArea>
            </chartareas>
        </asp:Chart>

Example 1 中的代码会指示 Chart 控件生成柱状图的 JPEG 图像，并将其写入临时目录 ~/Temporary/Graph 中。在该控件将此图像写入磁盘后，用户浏览器随后会对该文件发起一次请求，并将其显示给用户。该图像未安全写入磁盘。此外，该代码会假定底层基础架构会保护该文件，使其免受其他用户未经授权的访问。
