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
In systems using the optional capture & replay functionality of SAP HANA, 1.00 and 2.00, (see SAP Note 2362820 for more information about capture & replay), user credentials may be stored in clear text in the indexserver trace files of the control system. An attacker with the required authorizations on the control system may be able to access the user credentials and gain unauthorized access to data in the captured or target system.

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

In SAP HANA 1.00 and 2.00 systems using the optional capture & replay functionality (SAP Note 2362820), user credentials are stored in clear text within indexserver trace files on the control system. An attacker with appropriate system authorizations can read these plaintext credentials and use them to access captured or target systems.

MitigationApply the SAP patch for CVE-2018-2402, rotate all credentials that may have been exposed in trace files, and configure trace file sanitization to prevent future credential leakage.

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. Check SAP HANA version
    Execute 'SELECT * FROM M_DATABASE' or 'HDB version' command to determine if the installed version is 1.00 or 2.00
    Affected if Version is 1.00 or 2.00 and matches the affected range
  2. Determine if capture & replay is enabled
    Check configuration for the capture & replay functionality as described in SAP Note 2362820. Look for active capture/replay processes or related configuration entries in the SAP HANA system.
    Affected if Capture & replay functionality is installed and active
  3. Locate indexserver trace files
    Find indexserver trace files in the SAP HANA diagnostic directory (typically under $SAPTRACE/$HOSTNAME/host*_indexserver_*.trc)
    Affected if Trace files exist on the control system
  4. Inspect trace files for plaintext credentials
    Search within indexserver trace files for patterns matching user credentials, passwords, or authentication tokens in clear text. Use grep or similar to search for password-related strings.
    Affected if Readable plaintext credentials are found in trace files

User is affected if running SAP HANA 1.00 or 2.00, capture & replay is enabled, and indexserver trace files contain plaintext credentials.
