CVE-2019-0388
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 UI5 HTTP Handler (corrected in SAP_UI versions 7.5, 7.51, 7.52, 7.53, 7.54 and SAP UI_700 version 2.0) allows an attacker to manipulate content due to insufficient URL validation.
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 confidenceThe vulnerability exists in SAP UI5 HTTP Handler due to insufficient URL validation, which allows attackers to manipulate content through crafted malicious URLs.

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 installed SAP_UI versionCheck the SAP_UI component version using transaction SMICM (ICM Monitor) or by reviewing the SAP system information via transaction System > Status. Look for the SAP_UI component version listed.Affected if The installed SAP_UI version exactly matches 2.0, 7.5, 7.51, 7.52, 7.53, or 7.54.
-
Confirm UI5 application is accessibleDetermine if any UI5-based applications are running in the SAP system by checking the ICM HTTP ports (default 50000) or by reviewing active ICF services via transaction SICF. Look for /sap/bc/ui5_ui5 paths being served.Affected if UI5 applications are accessible and the SAP_UI version matches the affected versions.
-
Verify HTTP handler is activeReview the ICM configuration via transaction SMICM by choosing Goto > Parameters > Display. Check for UI5-related handler configurations or examine the ICF nodes under /sap/bc/ui5_ui5 in transaction SICF.Affected if The UI5 HTTP handler is active and the version is in the affected list.
A system is affected if it runs SAP_UI version 2.0, 7.5, 7.51, 7.52, 7.53, or 7.54 and has UI5 applications served through the HTTP handler.

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 patched SAP_UI versions (7.5, 7.51, 7.52, 7.53, 7.54 or SAP UI_700 version 2.0) or later, which contain proper URL validation fixes. Prior to production deployment, validate in a staging environment.
