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 · unedited
IBM Concert Software 1.0.0 through 1.1.0 is vulnerable to cross-site scripting. This vulnerability allows an authenticated user 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 confidence

IBM Concert Software versions 1.0.0 through 1.1.0 contains a stored cross-site scripting (XSS) vulnerability in its Web UI. An authenticated attacker can inject arbitrary JavaScript code into the application interface, which executes in the browsers of other users viewing the affected content, potentially exfiltrating credentials or session tokens within a trusted session context.

MitigationImplement context-aware output encoding for all user-supplied data displayed in the Web UI and add robust input validation. Apply Content Security Policy headers to restrict script execution. Upgrade to a patched version when available from IBM.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm IBM Concert installation
    Locate IBM Concert Software in your environment. Check for the installation directory, service, or container image that hosts the product.
    Affected if IBM Concert Software is present in the environment.
  2. Identify installed version
    Run the product's version command, check the about page in the Web UI, or inspect version files in the installation directory to determine the exact version number.
    Affected if The installed version is 1.0.0, 1.0.1, 1.0.2, 1.1.0, or any version in the range 1.0.0 <= version < 2.0.0.
  3. Verify Web UI is enabled
    Confirm the Web UI component is accessible by accessing the application's HTTP/HTTPS endpoint in a browser or via curl/curl equivalent.
    Affected if The Web UI is exposed and accessible to users.
  4. Check authentication configuration
    Review authentication settings to determine if user accounts can be created and if the login interface is functional.
    Affected if User authentication is enabled and allows authenticated users to submit content to the Web UI.

You are affected if IBM Concert version 1.0.0 through 1.1.0 is installed with the Web UI component enabled and user authentication is configured, allowing authenticated users to input content that gets stored and displayed to other users.

Upgrade available Upgrade to 2.0.0 or later
Fixed in 2.0.0
Interim mitigation

Implement context-aware output encoding for all user-supplied data displayed in the Web UI and add robust input validation. Apply Content Security Policy headers to restrict script execution. Upgrade to a patched version when available from IBM.

Recommended fix Moderate confidence

IBM Concert 2.0.0 or later

  1. 1. Back up the current IBM Concert installation and configuration
  2. 2. Review IBM Concert 2.0.0 release notes and migration documentation
  3. 3. Test the upgrade in a non-production environment first
  4. 4. Perform the upgrade to IBM Concert version 2.0.0 or later
  5. 5. Verify the XSS vulnerability is remediated by testing the affected functionality
  6. 6. Validate that all existing workflows and integrations function correctly post-upgrade
Caveat Major version upgrades often include breaking changes; review migration guide for configuration and API adjustments
