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
The Data Provisioning Agent (aka DP Agent) in SAP HANA does not properly restrict access to service functionality, which allows remote attackers to obtain sensitive information, gain privileges, and conduct unspecified other attacks via unspecified vectors, aka SAP Security Note 2262742.

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

The Data Provisioning Agent in SAP HANA contains an improper access control vulnerability where service functionality is not properly restricted, allowing remote unauthenticated attackers to bypass authorization and access sensitive service endpoints. This enables information disclosure and privilege escalation through unspecified attack vectors.

MitigationImplement proper authentication and authorization controls on all DP Agent service endpoints to restrict access to authorized users and systems only. Apply SAP Security Note 2262742 which provides the vendor patch for this access control deficiency.

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 HANA Data Provisioning Agent is installed
    Locate DP Agent installation by checking for its binaries and service processes. On Windows, look in the installation directory (commonly under C:\usr\sap\hdb\dp\ or similar). On Linux, check /usr/sap/hdb/dp/ or the SAP HANA installation path. Verify the DP Agent service process is running.
    Affected if The DP Agent software is installed and running on the system.
  2. Identify DP Agent network listeners
    Use netstat or equivalent command to find ports where DP Agent services are listening. Look for typical DP Agent ports in the range 3000-3999 or check SAP HANA studio for configured DP Agent ports. Document all listening endpoints and their IP bindings (0.0.0.0 vs 127.0.0.1).
    Affected if DP Agent services are listening on network interfaces accessible to untrusted networks.
  3. Verify if DP Agent endpoints require authentication
    Attempt to access common DP Agent service endpoints without credentials. Common paths include the HTTP/HTTPS services used for data provisioning. Use curl or similar tool to send requests to the exposed ports without providing authentication headers or credentials.
    Affected if Service endpoints respond successfully without requiring any authentication credentials.
  4. Review DP Agent configuration for authorization settings
    Examine the DP Agent configuration files (typically in the config directory of the DP Agent installation) for authentication and authorization settings. Check for any misconfigurations that allow anonymous or unauthenticated access to sensitive service functions.
    Affected if Configuration files show authentication is disabled or improperly configured for service endpoints.
  5. Check network exposure of DP Agent services
    Determine if DP Agent ports are exposed to external/untrusted networks by reviewing firewall rules, network segmentation, and routing configurations. Verify whether the listening interfaces are bound to internal-only networks versus public-facing interfaces.
    Affected if DP Agent services are reachable from networks outside the trusted internal environment without proper network segmentation.

A user is affected if the Data Provisioning Agent is installed and its service endpoints are accessible without authentication, particularly if exposed to untrusted networks.
