CVE-2018-2464
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 WebDynpro Java, versions 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in a stored Cross-Site Scripting (XSS) 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 · high confidenceSAP WebDynpro Java versions 7.20-7.50 contains a stored Cross-Site Scripting (XSS) vulnerability due to insufficient encoding of user-controlled inputs. Attackers can inject malicious scripts that persist in the application and execute in users' browsers when the stored content is rendered.

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 NetWeaver with WebDynpro Java is deployedCheck if the SAP system is running by accessing SAP transaction codes like SM51 or by querying the SAP startsap script output. Verify WebDynpro Java component is installed by checking SAP transaction SDNW or via the SAP NetWeaver Administrator.Affected if SAP NetWeaver with WebDynpro Java component is present in the environment
-
Identify the SAP NetWeaver versionExecute SAP transaction SM51 to view the NetWeaver release and version, or use SAP transaction NWVersion to check the specific version number. The version should match 7.20, 7.30, 7.31, 7.40, or 7.50.Affected if The installed NetWeaver version is 7.20, 7.30, 7.31, 7.40, or 7.50
-
Verify WebDynpro Java applications are accessibleCheck if WebDynpro applications are accessible via SAP Logon or web URLs using the pattern /webdynpro/dispatcher/sap/<component_name>. Use transaction WD_ANALYZE_TOOLS or SRT_UTIL to enumerate active WebDynpro components.Affected if WebDynpro Java applications are deployed and accessible
-
Identify user input fields in WebDynpro applicationsReview WebDynpro application configurations using transaction SE80 or WD_ANALYZE_TOOLS. Examine the application for input fields that accept user data and are rendered back without encoding.Affected if WebDynpro applications contain input fields that accept and display user-controlled data
The environment is affected if SAP NetWeaver version 7.20-7.50 with WebDynpro Java is deployed and applications contain user input fields that are rendered without proper encoding.

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 dataImplement proper output encoding for all user-controlled inputs rendered in WebDynpro Java components, following OWASP XSS prevention guidelines. Identify and sanitize all data display points in the affected application.
