ASP.NET Misconfiguration: Missing Custom Error Page

Description

An ASP .NET application must enable custom error pages in order to prevent attackers from mining information from the framework's built-in responses.

Common Consequences

Scope:
Confidentiality
Impact:
Read Application Data
Notes:
Default error pages gives detailed information about the error that occurred, and should not be used in production environments. Attackers can leverage the additional information provided by a default error page to mount attacks targeted on the framework, database, or other resources used by the application.
