CWE-11: ASP.NET Misconfiguration: Creating Debug Binary
ASP.NET Misconfiguration: Creating Debug Binary
Weakness ID: 11 (Weakness Variant)
Status: Draft
Description
Description Summary
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.

Common Consequences
Scope
Effect
Confidentiality
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)
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
Description
Avoid releasing debug binaries into the production environment. Change
the debug mode to false when the application is deployed into production
(See demonstrative example).
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.
