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 · uneditedReflected cross-site scripting vulnerability in SAP internet Graphics Server, 7.20, 7.20EXT, 7.45, 7.49, 7.53.
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 confidenceReflected cross-site scripting (XSS) vulnerability in SAP Internet Graphics Server affecting versions 7.20, 7.20EXT, 7.45, 7.49, and 7.53. The vulnerability allows attackers to inject malicious scripts through reflected parameters, potentially compromising user sessions or stealing credentials.

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 Internet Graphics Server is installedCheck for running processes or services related to SAP IGS on the system. Look for SAP Internet Graphics Server in installed programs or running services.Affected if SAP Internet Graphics Server is found running or installed on the system
-
Identify the installed IGS versionQuery the installed SAP Internet Graphics Server version using SAP administration tools, configuration files, or version inspection methods appropriate for the SAP installation.Affected if The version matches 7.20, 7.20EXT, 7.45, 7.49, or 7.53
-
Verify web interface exposureDetermine if the IGS web endpoints are accessible over HTTP/HTTPS. Check network listener configurations and firewall rules for port 80, 443, or custom IGS ports.Affected if The IGS web interface is exposed and accessible to network users or attackers
-
Test for reflected parameter handlingSubmit a benign test payload (such as a harmless script or alert) through IGS URL parameters and observe if the input is reflected back in the response without proper encoding.Affected if User-supplied input in URL parameters is reflected in the HTTP response without sanitization
A defender is affected if SAP Internet Graphics Server versions 7.20, 7.20EXT, 7.45, 7.49, or 7.53 are installed and the IGS web interface is accessible, allowing reflected parameters to be injected and reflected in server responses.

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 SAP security patches for CVE-2018-2383 and implement input validation/sanitization on affected server endpoints. Consider deploying a web application firewall as an additional protective measure.
