CVE-2018-2416
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 Identity Management 7.2 and 8.0 do not sufficiently validate an XML document accepted from an untrusted source.
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 Identity Management versions 7.2 and 8.0 fail to properly validate XML documents from untrusted sources, allowing XML External Entity (XXE) injection attacks. An attacker can exploit this by submitting malicious XML containing external entity references to extract sensitive data, perform Server-Side Request Forgery (SSRF), or denial of service.

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 SAP Identity Management versionLocate the installed version of SAP Identity Management in the system by checking the software inventory, About dialog, or version file (commonly found in installation directory or administrative console)Affected if The installed version is exactly 7.2 or exactly 8.0
-
Determine if XML input is accepted from external sourcesReview the system configuration or deployment documentation to identify if SAP Identity Management accepts or processes XML documents from untrusted/network sources, such as through import functions, identity data feeds, or integration endpointsAffected if XML documents from untrusted or external sources are accepted and processed by the system
-
Inspect XML parser configurationLocate the XML parser or XML processor configuration files used by SAP Identity Management (typically in the application configuration directory) and check whether settings for external entity processing, DTD processing, or external schema validation are enabledAffected if The XML parser is configured to allow external entities, DTD processing, or external schema validation (i.e., not explicitly disabled)
A system is affected if it runs SAP Identity Management version 7.2 or 8.0 AND accepts XML input from untrusted sources with an XML parser that has not disabled external entity processing.
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 dataConfigure XML parsers to disable external entity processing and enable strict schema validation. Apply vendor patches when available and validate/sanitize all XML input from untrusted sources.
