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
Under certain circumstances, a specific endpoint of the Controller's API could be misused by unauthenticated users to execute SQL statements that deliver information about system configuration in SAP HANA Extended Application Services, 1.0.

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

An unauthenticated SQL injection vulnerability in the Controller API endpoint of SAP HANA Extended Application Services (XS) 1.0 allows remote attackers to execute arbitrary SQL statements and retrieve system configuration information without any authentication credentials.

MitigationApply the relevant SAP security patch for CVE-2018-2373 and implement network-level access controls to restrict exposure of the vulnerable Controller API endpoint until the patch is deployed.

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 SAP HANA XS installation
    Check the SAP HANA system for the presence of SAP HANA Extended Application Services (XS) 1.0 by querying the SAP HANA instance metadata or checking installed packages: SELECT * FROM M_COMPONENTS WHERE COMPONENT_NAME LIKE '%XS%';
    Affected if The component version returned is exactly 1.0 (XS 1.0)
  2. Verify Controller API endpoint exposure
    Confirm the SAP HANA XS Controller API endpoint is network-accessible. This endpoint is typically exposed on port 80/443 under paths like /sap/hana/xs/controller/ or similar XS routing paths. Check your web server or SAP HANA XS configuration files for exposed routes.
    Affected if The Controller API endpoint is externally accessible without authentication requirements configured at the network or application layer
  3. Check for unauthenticated access to Controller API
    Attempt a simple unauthenticated HTTP request to the Controller API endpoint (e.g., GET /sap/hana/xs/controller/) from an untrusted network perspective. If the system returns a response rather than rejecting the request with authentication challenges, the endpoint may be exposed.
    Affected if The endpoint responds to unauthenticated requests with valid API data or configuration information instead of requiring authentication
  4. Review XS security configuration
    Inspect the SAP HANA XS configuration files (xsconfig.ini, xssec.properties) and the xsengine process configuration for authentication enforcement on the Controller API. Look for settings that disable authentication for the controller endpoint.
    Affected if Authentication is disabled or not enforced on the Controller API endpoint in the XS configuration

A system is affected if it runs SAP HANA XS 1.0 with the Controller API endpoint exposed and unauthenticated access permitted.
