CVE-2025-33084
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 · uneditedIBM Concert Software 1.0.0 through 1.1.0 could allow a remote attacker to obtain sensitive information, caused by the failure to properly enable HTTP Strict Transport Security. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques.
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 · high confidenceIBM Concert Software versions 1.0.0 through 1.1.0 fails to enable HTTP Strict Transport Security (HSTS) headers, allowing man-in-the-middle attackers to intercept sensitive information by intercepting or modifying HTTP traffic between clients and the server.

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.
-
Confirm IBM Concert installationLocate the IBM Concert installation directory or check system services for 'IBM Concert' or 'concert' processes runningAffected if IBM Concert is not installed on the system
-
Identify installed versionRun 'concert --version' or check the version file in the installation directory if available, then compare against the affected range 1.0.0 to 1.1.0Affected if Installed version is 1.0.0, 1.0.x, or 1.1.0 (any version >= 1.0.0 and < 2.0.0)
-
Verify HSTS header presenceSend an HTTP request to the IBM Concert web interface (e.g., curl -I http://<hostname>:<port>) and inspect response headers for 'Strict-Transport-Security'Affected if The Strict-Transport-Security header is missing from HTTP responses
A user is affected if IBM Concert version 1.0.0 through 1.1.0 is running AND the Strict-Transport-Security header is not present in HTTP responses from the server.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.0.0
Enable HSTS by configuring the web server or application to include the Strict-Transport-Security header in all HTTP responses, with appropriate max-age and includeSubDomains directives.
IBM Concert 2.0.0 or later
- Verify current IBM Concert version using product-specific command or admin console
- Review IBM Concert 2.0.0 release notes for migration requirements and breaking changes
- Create backup of current configuration and data
- Upgrade IBM Concert to version 2.0.0 or later following IBM's standard upgrade documentation
- Verify HSTS is now properly enabled post-upgrade
- Test application functionality to ensure upgrade was successful
