Information Exposure Through Debug Information

结构: Simple

Abstraction: Variant

状态: Draft

被利用可能性: unkown

基本描述

可能的缓解方案

Implementation

策略:

Do not leave debug statements that could be executed in the source code. Assure that all debug information is eradicated before releasing the software.

MIT-46 Architecture and Design

策略: Separation of Privilege

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design and that the compartmentalization serves to allow for and further reinforce privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide when it is appropriate to use and to drop system privileges.

示例代码

例

The following program changes its behavior based on a debug flag.

bad JSP

<% if (Boolean.getBoolean("debugEnabled")) {

%>
User account number: <%= acctNo %>
<%
} %>

The code writes sensitive debug information to the client browser if the "debugEnabled" flag is set to true .
