CWE-215: Information Exposure Through Debug Information

Weakness ID: 215
Abstraction: Variant
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The application contains debugging code that can expose sensitive information to untrusted parties.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

+ Applicable Platforms
The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.

+ Common Consequences

The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

Technical Impact: Read Application Data

+ Demonstrative Examples

Example 1

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

(bad)
Example Language: 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 .

+ Observed Examples
ReferenceDescription
Password exposed in debug information.
CGI script includes sensitive information in debug messages when an error is triggered.
FTP client with debug option enabled shows password to the screen.
+ Potential Mitigations

Phase: Implementation

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

Phase: Architecture and Design

Strategy: 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.
