Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in ExonautWeb in 4C Strategies Exonaut 21.6. There are verbose error messages.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceExonautWeb in 4C Strategies Exonaut version 21.6 contains verbose error messages that expose sensitive system information, potentially including stack traces, file paths, configuration details, or version information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Exonaut versionLocate the ExonautWeb application version information, typically found in the application metadata, assembly info, or version file shipped with the installation. Check the application binary or version manifest for the exact version number.Affected if The installed version is exactly 21.6, as this is the only affected version listed.
-
Identify error handling configurationLocate the application configuration file for ExonautWeb, commonly named web.config, app.config, or a similar configuration file in the application root directory.Affected if The configuration file exists and contains settings related to error handling or custom error pages.
-
Check customErrors mode settingIf a web.config file exists, examine the system.web/customErrors section. Look for the 'mode' attribute which controls error message verbosity.Affected if The customErrors mode is set to 'Off' or is missing, which would enable detailed error messages to be displayed to users.
-
Check errorMode setting in newer frameworksIf the application uses ASP.NET Core or newer framework configuration, check the appSettings or Startup.cs for custom exception handling middleware that may expose stack traces.Affected if Error handling configuration allows detailed exception information (stack traces) to be returned in HTTP responses.
-
Inspect response for sensitive error contentTrigger a deliberate error condition in the application (such as accessing a non-existent resource or providing invalid input) and observe the HTTP response for exposed internal paths, stack traces, or database structure information.Affected if Error responses contain detailed system information including file paths, stack traces, or configuration details.
A user is affected if they are running Exonaut version 21.6 AND the application is configured to display verbose error messages with sensitive system details.
