The underlying weakness: Server-generated Error Message Containing Sensitive Information
Certain conditions, such as network failure, will cause a server error message to be displayed.
How developers prevent this class of flaw
- Recommendations include designing and adding consistent error handling mechanisms which are capable of handling any user input to your web application, providing meaningful detail to end-users, and preventing error messages that might provide information useful to an attacker from being displayed.
