CWE-11: ASP.NET Misconfiguration: Creating Debug Binary

Weakness ID: 11
Abstraction: Variant
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
Debugging messages help attackers learn about the system and plan a form of attack.
+ Extended Description
ASP .NET applications can be configured to produce debug binaries. These binaries give detailed debugging messages and should not be used in production environments. Debug binaries are meant to be used in a development or testing environment and can pose a security risk if they are deployed to production.
+ 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.

+ Relevant to the view "Research Concepts" (CWE-1000)
NatureTypeIDName
ChildOfVariantVariant - a weakness that is described at a very low level of detail, typically limited to a specific language or technology. More specific than a Base weakness.215Information Exposure Through Debug Information
+ Relevant to the view "Development Concepts" (CWE-699)
NatureTypeIDName
MemberOfCategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic.519.NET Environment Issues
+ Background Details
The debug attribute of the <compilation> tag defines whether compiled binaries should include debugging information. The use of debug binaries causes an application to provide as much information about itself as possible to the user.
+ Modes Of Introduction

The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the software life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

+ 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.

Confidentiality

Technical Impact: Read Application Data

Attackers can leverage the additional information they gain from debugging output to mount attacks targeted on the framework, database, or other resources used by the application.
+ Demonstrative Examples

Example 1

The file web.config contains the debug mode setting. Setting debug to "true" will let the browser display debugging information.

(bad code)
Example Language: XML 
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation
defaultLanguage="c#"
debug="true"
/>
...
</system.web>
</configuration>

Change the debug mode to false when the application is deployed into production.

+ Potential Mitigations

Phase: System Configuration

Avoid releasing debug binaries into the production environment. Change the debug mode to false when the application is deployed into production.
+ Memberships
This MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.
