CVE-2025-42885
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 · uneditedDue to missing authentication, SAP HANA 2.0 (hdbrss) allows an unauthenticated attacker to call a remote-enabled function that will enable them to view information. As a result, it has a low impact on the confidentiality but no impact on the integrity and availability of the 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 · moderate confidenceSAP HANA 2.0's hdbrss component lacks authentication, allowing unauthenticated attackers to invoke remote-enabled functions and view sensitive information. The vulnerability has low confidentiality impact with no integrity or availability impact.

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 installation and versionUse SAP HANA database tools or system queries to retrieve the installed SAP HANA version (e.g., select * from m_database or hdbversion command). Compare the version to SAP HANA 2.0 baseline releases.Affected if The system is running SAP HANA 2.0 and the version falls within the affected release range.
-
Verify hdbrss component statusQuery the SAP HANA system to determine whether the hdbrss (remote subscription server) component is enabled. This may be checked via SQL query (e.g., SELECT * FROM M_SERVICES where SERVICE_NAME = 'hdbrss') or through SAP HANA administration tools.Affected if The hdbrss service is actively running or enabled on the SAP HANA instance.
-
Confirm authentication configuration for remote function interfaceExamine the hdbrss configuration or remote function call settings to determine if authentication is enforced for the remote function interface. Look for configuration parameters related to authentication, authorization, or secure remote access.Affected if Authentication is disabled, not configured, or set to allow anonymous access for the hdbrss remote function interface.
-
Review network exposure of hdbrss endpointCheck network listener configuration or firewall rules to determine if the hdbrss service port is exposed to untrusted networks or accessible externally.Affected if The hdbrss service is listening on a network interface accessible from untrusted or public networks.
A user is affected if they run SAP HANA 2.0 with the hdbrss component enabled and the remote function interface lacks authentication, particularly when exposed to untrusted network segments.

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 dataEnable authentication for the hdbrss remote function interface and restrict network access to trusted sources to prevent unauthorized calls.
