CVE-2025-36153
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 1.0.0 through 2.0.0 is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
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 confidenceIBM Concert versions 1.0.0 through 2.0.0 contains a stored XSS vulnerability in its Web UI. An unauthenticated attacker can inject malicious JavaScript code that gets stored and executed in the browsers of users accessing the compromised interface, potentially leading to session hijacking and credential theft.

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.
-
Identify installed IBM Concert versionLocate the installed version of IBM Concert by checking product documentation for version detection methods (such as version file, command-line tool, or admin interface)Affected if version is 1.0.0 through 2.0.x (any version >= 1.0.0 and < 2.1.0)
-
Verify Web UI component is activeConfirm the IBM Concert Web UI component is enabled and network-accessibleAffected if Web UI is exposed and version is within the vulnerable range
-
Compare version against CVE rangeMatch your installed version against the affected range: versions 1.0.0 through 2.0.x are vulnerableAffected if installed version falls within >= 1.0.0 and < 2.1.0
A user is affected if IBM Concert version 1.0.0 through 2.0.x is running with the Web UI component accessible.

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 · scoped2.1.0
Apply vendor patches from IBM for Concert. Until patched, implement output encoding and input validation on all user-supplied data in the Web UI, and configure appropriate session timeouts to limit exposure.
2.1.0
- 1. Back up the current IBM Concert configuration and data according to your organization's backup procedures.
- 2. Review IBM Concert 2.1.0 release notes for any migration requirements or prerequisites.
- 3. Stop the IBM Concert service.
- 4. Upgrade IBM Concert from the current version (1.0.0-2.0.0) to version 2.1.0 or later.
- 5. Verify the upgrade was successful by checking the service status and version number.
- 6. Test the Web UI functionality to confirm the XSS vulnerability is remediated.
- 7. Verify that the intended functionality is working correctly after the upgrade.
