Discussion

Any application providing too much information in error messages risks compromising the data and security of the application and system. The structure and content of error messages must be carefully considered by the organization and development team. Organizations carefully consider the structure/content of error messages. The extent to which information systems are able to identify and handle error conditions is guided by organizational policy and operational requirements. Information that could be exploited by adversaries includes erroneous logon attempts with passwords entered by mistake as the username, mission/business information that can be derived from (if not stated explicitly by) information recorded, and personal information such as account numbers, social security numbers, and credit card numbers.

Check Content

Review the application documentation and deployed configuration to determine if error messages generated by the application only provide the information necessary for corrective actions without revealing information that could be exploited.

If error messages contain information that could be exploited, this is a finding.
