CVE-2019-0277
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 · uneditedSAP HANA extended application services, version 1, advanced does not sufficiently validate an XML document accepted from an authenticated developer with privileges to the SAP space (XML External Entity vulnerability).
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 extended application services version 1 advanced does not properly validate incoming XML documents, allowing an authenticated developer with SAP space privileges to inject malicious XML External Entities (XXE). This can enable the attacker to read internal files, perform Server-Side Request Forgery (SSRF), or cause Denial of Service by exploiting the XML parser's handling of external entity references.

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.
-
Verify SAP HANA XS version 1.0 is installedUse SAP HANA administration tools or query the system to determine the installed version of SAP HANA extended application services (XS advanced). Compare your installed version against the affected range.Affected if The installed version is exactly 1.0 (Sap Hana Extended Application Services = 1.0)
-
Confirm XML document processing is in useIdentify whether applications or services in the SAP HANA XS advanced environment accept and process XML documents, particularly through user-provided XML input.Affected if XML document processing or validation features are actively used by any XS advanced application
-
Audit developer accounts with SAP space privilegesReview user role assignments in the SAP HANA system to identify authenticated developers who have been granted SAP space privileges in the XS advanced framework.Affected if There are users with developer roles assigned SAP space privileges
-
Inspect XML parser external entity configurationExamine the SAP HANA XML parser configuration settings to determine whether external entity processing is enabled. Check the parser configuration for settings related to XXE protection or external entity resolution.Affected if The XML parser is configured to allow or does not explicitly disable external entity processing
You are affected if SAP HANA XS 1.0 is running with XML processing enabled and developers have SAP space privileges, especially if the XML parser permits external entity references.
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 dataDisable XML external entity processing in the SAP HANA XML parser configuration, implement strict input validation for XML documents, and apply available SAP security patches for this vulnerability.
