CVE-2018-2369
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, 1.00, 2.00, allows an unauthenticated attacker to access information which would otherwise be restricted. An attacker can misuse the authentication function of the SAP HANA server on its SQL interface and disclose 8 bytes of the server process memory. The attacker cannot influence or predict the location of the leaked memory.
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 confidenceSAP HANA versions 1.00 and 2.00 contain an information disclosure vulnerability in the SQL interface authentication function. An unauthenticated attacker can exploit this to leak 8 bytes of server process memory. The memory disclosure is unintentional and the attacker cannot control or predict the memory location.

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.
-
Confirm SAP HANA installation and versionExecute 'HDB version' or check the SAP HANA installation directory for version information. The version can also be obtained via SQL: SELECT VERSION FROM M_DATABASE;Affected if The installed version is exactly 1.00 or 2.00
-
Verify SQL interface is enabledCheck the SAP HANA configuration for the SQL endpoint. This is typically exposed on port 30015 (tenant) or 30013 (system). Query: SELECT * FROM M_SERVICES WHERE SERVICE_NAME = 'indexserver';Affected if SQL interface service is running and accessible
-
Check network exposure of SQL portReview network configuration and firewall rules to determine if the SQL port (30013, 30015) is reachable from untrusted networks. Use netstat or ss commands: netstat -an | grep -E '30013|30015'Affected if SQL interface port is exposed to untrusted or public network segments
-
Verify authentication configurationCheck the SQL interface authentication settings in SAP HANA. Review the xsadvanced or webdispatcher configuration for authentication mechanisms. The vulnerability exists in the authentication function itself.Affected if SQL interface authentication is active (which is the default configuration)
You are affected if SAP HANA version 1.00 or 2.00 is installed and the SQL interface is network-accessible, as the flaw resides in the authentication function of the SQL interface.
Generated from the published advisory. Verify against your own configuration.
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 dataApply the relevant SAP security patch for CVE-2018-2369. Until patched, restrict network access to the SAP HANA SQL interface to trusted sources only.
