Self-generated Error Message Containing Sensitive Information
The product identifies an error condition and creates its own diagnostic or error messages that contain sensitive information.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
The following code uses custom configuration files for each user in the application. It checks to see if the file exists on the system before attempting to open and use the file. If the configuration file does not exist, then an error is generated, and the application exits.
If this code is running on a server, such as a web application, then the person making the request should not know what the full pathname of the configuration directory is. By submitting a username that is not associated with a configuration file, an attacker could get this pathname from the error message. It could then be used to exploit path traversal, symbolic link following, or other problems that may exist elsewhere in the application.
