CVE-2018-2392
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 Internet Graphics Server (IGS) 7.20, 7.20EXT, 7.45, 7.49, 7.53, fails to validate XML External Entity appropriately causing the SAP Internet Graphics Server (IGS) to become unavailable.
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 Internet Graphics Server (IGS) versions 7.20 through 7.53 fail to properly validate XML External Entities (XXE), allowing malicious XML input to cause denial of service and potentially expose internal resources.

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 IGS installationLocate the SAP Internet Graphics Server installation directory or check SAP system components using SAP administration tools (e.g., SAP MII transaction, SAP MCOD, or system landscape directory). Confirm the IGS component is present.Affected if SAP IGS is not installed on the system.
-
Determine SAP IGS versionQuery the installed SAP IGS version using SAP transaction code SM51 (release notes), or check the IGS binary/library version in the installation directory, or use SAP SAR or SAP JVM version checks if applicable.Affected if The installed version matches 7.20, 7.20ext, 7.45, 7.49, or 7.53.
-
Confirm XML processing is enabledIdentify if the IGS XML/mapping services are active or accessible. Check IGS configuration files (e.g., igs.xml, http Provider configuration) or SAP IGS monitoring endpoints for exposed XML parser functionality.Affected if XML input processing or XML mapping services are enabled and reachable via HTTP/HTTPS endpoints.
-
Inspect XML parser external entity configurationReview SAP IGS XML parser configuration files or SAP security settings for external entity processing. Check whether the XML parser allows external entity resolution or DTD processing.Affected if External entity processing or DTD processing is enabled in the XML parser configuration for SAP IGS.
A system is affected if SAP IGS versions 7.20, 7.20ext, 7.45, 7.49, or 7.53 are installed AND XML processing services are exposed AND external entity processing is enabled in the XML parser.
