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
Injection vulnerabilities due to validation/sanitisation of user-supplied input in ActiveMatrix BusinessWorks and Enterprise Administrator allows information disclosure, including exposure of accessible local files and host system details, and may allow manipulation of application behaviour.

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

This is an injection vulnerability in TIBCO ActiveMatrix BusinessWorks and Enterprise Administrator caused by improper validation and sanitization of user-supplied input. The flaw allows attackers to expose local files and host system details through the application, and may enable manipulation of application behavior through injected input.

MitigationImplement strict input validation and sanitization for all user-supplied data, restrict file access permissions, and apply principle of least privilege to limit exposure of system files and details.

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 product installation
    Locate TIBCO ActiveMatrix BusinessWorks or Enterprise Administrator on the system. Check common installation paths such as /opt/tibco, C:\tibco, or use system package/query tools to list installed TIBCO software.
    Affected if Either TIBCO ActiveMatrix BusinessWorks or Enterprise Administrator is present on the system
  2. Determine installed version
    Locate version information for the TIBCO product. Check for version files in the installation directory, manifest files, or use vendor-provided command-line tools to query the installed version.
    Affected if The installed version falls within the vulnerable version range for this CVE
  3. Verify exposed interfaces
    Review network configuration to determine if the application HTTP/API endpoints are accessible from untrusted networks. Check firewall rules, reverse proxy configurations, and application binding settings.
    Affected if The application REST/API or web interfaces are exposed to external or untrusted network sources
  4. Inspect input handling logs
    Review TIBCO application logs for suspicious patterns, error messages indicating file access attempts, host system information leakage, or malformed user input that could indicate exploitation attempts.
    Affected if Logs show evidence of injection attempts or unexpected file/system information exposure

If TIBCO ActiveMatrix BusinessWorks or Enterprise Administrator is running and its interface accepts user-supplied input, compare your version against the affected range to determine if you are vulnerable to this injection flaw.
