Vulnerability 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 needs to 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, for example, 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

Examine product documentation and code. If error messages do not limit information provided to only that which is necessary for corrective actions, this is a finding.

Fix text

Configure the Mainframe Product to limit information provided to only that which is necessary for corrective actions.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
