Executive Summary

IBM Concert versions 1.0.0 through 3.0.0 may expose sensitive technical error messages in the browser. These messages could reveal system details to remote attackers, potentially aiding further exploitation of the system.

Detection Guidance

This vulnerability involves IBM Concert returning detailed technical error messages in the browser. To detect it, monitor web server responses for verbose error messages containing sensitive information. Check HTTP response headers and error logs for stack traces or internal details. Use tools like curl to inspect responses: curl -v http://target-url. Look for HTTP 5xx errors or messages exposing system internals.

Impact Analysis

An attacker could gather system information from error messages, which might help them launch additional attacks against the affected IBM Concert instance. This could lead to unauthorized access or data breaches.

Compliance Impact

This vulnerability could expose sensitive information through detailed error messages, which may violate GDPR's data protection principles if personal data is leaked. For HIPAA, it might compromise protected health information if such data is revealed in error messages.

Mitigation Strategies

Disable detailed technical error messages in the browser to prevent sensitive information disclosure. Review and update error handling configurations in IBM Concert to ensure minimal information is exposed in error responses.
