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 Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2 is vulnerable to stored cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 214032.

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 Jazz Team Server versions 6.0.6 through 7.0.2 contains a stored cross-site scripting (XSS) vulnerability in its web interface. An authenticated user can inject malicious JavaScript code that persists on the server and executes in the browsers of other users viewing the affected content, potentially allowing session hijacking and credential theft within trusted sessions.

MitigationApply the IBM security patch or upgrade to a fixed version of IBM Jazz Team Server. Until the patch is applied, implement content security policies and educate users about suspicious links.

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. Identify the installed Jazz Team Server version
    Access the Jazz Team Server web interface and navigate to About > Version Details, or check the installLocation/server/serverconfig.properties file for the version property
    Affected if The displayed version is 6.0.6, 6.0.6.1, 7.0, 7.0.1, or 7.0.2
  2. Confirm the web application is accessible
    Attempt to reach the Jazz Team Server URL (typically https://hostname:9443/jts) in a web browser or via curl
    Affected if The web interface responds and displays a login or dashboard page
  3. Verify authentication is enabled
    Check the Jazz Team Server configuration at installLocation/server/conf/jts/processport.xml or through the Administer > Server > Security page to confirm authentication is not disabled
    Affected if The web interface accepts authenticated user sessions, which is required for the stored XSS to be exploitable

A user is affected if they run IBM Jazz Team Server versions 6.0.6 through 7.0.2 with the web interface accessible and authentication enabled.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the IBM security patch or upgrade to a fixed version of IBM Jazz Team Server. Until the patch is applied, implement content security policies and educate users about suspicious links.

Recommended fix Moderate confidence

Jazz Team Server 7.0.3 or later (7.0.4, 7.0.5, etc.)

  1. Identify your current IBM Jazz Team Server version from the About dialog in the web UI
  2. Download IBM Jazz Team Server version 7.0.3 or later from IBM Fix Central (https://www.ibm.com/support/fixcentral/)
  3. Review the IBM installation guide for upgrade procedures: https://www.ibm.com/docs/en/jazz/overview?topic=installing
  4. Create a complete backup of your existing Jazz Team Server data directory
  5. Stop the Jazz Team Server services before upgrading
  6. Install the new version following IBM's standard upgrade documentation
  7. After installation, verify the server starts successfully
  8. Confirm the XSS vulnerability is resolved by checking that user-supplied content is properly sanitized in the web UI
Caveat Review IBM's release notes for version 7.0.3+ for any configuration or compatibility changes; some custom plugins or integrations may require updates
