CVE-2019-0266
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 · uneditedUnder certain conditions SAP HANA Extended Application Services, version 1.0, advanced model (XS advanced) writes credentials of platform users to a trace file of the SAP HANA system. Even though this trace file is protected from unauthorized access, the risk of leaking information is increased.
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 confidenceSAP HANA XS Advanced (version 1.0) has a credential leakage vulnerability where platform user credentials are written to trace files under certain conditions. While trace files are access-protected, the presence of credentials in plaintext increases the risk of unauthorized disclosure.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify SAP HANA XS Advanced versionRun the command 'xs -v' or check the XSA admin UI for the installed version number. Alternatively, query the XSA landscape API for the runtime version.Affected if The installed version is exactly 1.0 (note: this affects only version 1.0, not later versions)
-
Locate XS Advanced trace filesAccess the XSA trace directory. Default path is under $XS_HOME/log/trace or via the SAP HANA studio under 'Diagnosis Files' for XSA components.Affected if Trace files exist in the standard XSA trace locations
-
Examine trace files for plaintext credentialsSearch trace files for patterns resembling credentials: look for keywords like 'password', 'pwd', 'credential', or base64-encoded strings that may appear immediately after authentication events. Use grep or similar tools on the trace directory.Affected if Any trace files contain plaintext user credentials or password strings
-
Check for authentication-related trace entriesReview trace files for entries generated during user authentication or platform user login events, as the vulnerability occurs under specific authentication conditions.Affected if Authentication events are logged in trace files during the timeframe the vulnerability could have been triggered
If running XSA version 1.0 and trace files contain plaintext credentials from platform user authentication, the environment is affected by this credential leakage vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReview and rotate any credentials that may have been written to trace files, and apply available SAP security patches. Audit trace file locations and implement additional access controls or automated cleanup of sensitive data from logs.
