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
The Web Server component of TIBCO Software Inc.'s TIBCO EBX contains an easily exploitable vulnerability that allows a low privileged attacker with network access to execute Stored Cross Site Scripting (XSS) on the affected system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s TIBCO EBX: versions 6.0.0 through 6.0.8.

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 confidence

Stored Cross-Site Scripting (XSS) vulnerability in TIBCO EBX Web Server allows low-privileged authenticated attackers to inject malicious scripts that persist in the application and execute when other users view the compromised content. The attack requires human interaction from a victim user.

MitigationUpgrade TIBCO EBX to a patched version beyond 6.0.8. As an interim control, implement strict input validation and output encoding on all user-supplied data fields, and consider restricting low-privilege user permissions until patching is complete.

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 TIBCO EBX version
    Locate the EBX installation directory and check version information files, typically found in the EBX server deployment or in the product documentation. Common locations include version properties files or the EBX administration console version display.
    Affected if The installed version is greater than or equal to 6.0.0 and less than 6.0.9 (e.g., 6.0.0 through 6.0.8.x)
  2. Confirm EBX Web Server is enabled
    Verify that the EBX Web Server component is running and accessible. This can be done by checking the web server status through the EBX administration interface or by confirming the web application is deployed and responding to HTTP/HTTPS requests.
    Affected if The EBX Web Server is active and accepting connections, exposing the vulnerable application interface
  3. Verify low-privilege user authentication is configured
    Check if the EBX application has user authentication enabled and supports low-privilege accounts. Review user role configurations in the EBX administration console or user management settings.
    Affected if Low-privilege authenticated users have access to the application and can submit content through user-facing forms or data entry interfaces
  4. Identify user-facing input fields
    Review which EBX screens and forms accept user-supplied data that gets stored and displayed to other users. Focus on content creation, data modeling, or record submission interfaces.
    Affected if User input fields exist that store and render content back to other users without sufficient output encoding

A user is affected if their TIBCO EBX installation runs version 6.0.0 through 6.0.8.x, the Web Server is accessible, and low-privilege users can submit content that gets displayed to other users.

Upgrade available Upgrade to 6.0.9 or later
Fixed in 6.0.9
Interim mitigation

Upgrade TIBCO EBX to a patched version beyond 6.0.8. As an interim control, implement strict input validation and output encoding on all user-supplied data fields, and consider restricting low-privilege user permissions until patching is complete.

Recommended fix High confidence

TIBCO EBX 6.0.9 or later

  1. Identify the current TIBCO EBX version installed in your environment
  2. Review the TIBCO EBX 6.0.9 release notes and upgrade documentation for any specific requirements
  3. Plan the upgrade following your organization's change management procedures
  4. Download TIBCO EBX version 6.0.9 or later from the TIBCO Support Portal
  5. Create a complete backup of the EBX configuration, database, and data directory
  6. Stop all EBX services and application servers running EBX
  7. Install TIBCO EBX version 6.0.9 using TIBCO's documented upgrade procedure
  8. Start the EBX services and verify the application is running correctly
