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
A code injection vulnerability exists in SAP TREX / Business Warehouse Accelerator (BWA). The vendor response is SAP Security Note 2419592.

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

A code injection vulnerability in SAP TREX / Business Warehouse Accelerator (BWA) allows remote attackers to inject malicious code. The critical CVSS score of 9.8 indicates potential for complete system compromise without authentication.

MitigationApply SAP Security Note 2419592 to patch the vulnerability. Restrict network access to TREX/BWA services and monitor for indicators of compromise until the patch is applied.

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 if SAP TREX is installed
    Check for TREX installation directories (typically under /usr/sap/<SID>/TREX or C:\Program Files\SAP\TREX) and look for TREX-related processes (trex*, trexd, trexindexserver)
    Affected if SAP TREX software is present on the system
  2. Identify if Business Warehouse Accelerator is running
    Check for BWA processes (bwaccel*, bwa*) and services, typically on ports 5100-5103 or custom ports configured during installation
    Affected if BWA processes or services are running
  3. Verify TREX/BWA network exposure
    Use netstat or similar tools to check if TREX/BWA ports (commonly 5100-5103, 8000-8004, 3300-3399 for TREX) are listening on non-loopback interfaces or publicly accessible
    Affected if TREX/BWA services are exposed to network addresses other than localhost
  4. Check for unauthorized access indicators
    Review TREX/BWA log files (under <TREX_install>/log directory) for unexpected commands, suspicious query patterns, or unknown admin access
    Affected if Logs show unexpected commands, unauthorized access attempts, or signs of code injection

If SAP TREX or BWA is installed and network-accessible, the environment is affected since all versions contain the vulnerability.
