CVE-2019-7847
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 · uneditedAdobe Campaign Classic version 18.10.5-8984 and earlier versions have an Improper Restriction of XML External Entity Reference ('XXE') vulnerability. Successful exploitation could lead to Arbitrary read access to the file system in the context of the current user.
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 confidenceAdobe Campaign Classic versions 18.10.5-8984 and earlier contain an XXE (XML External Entity) vulnerability that allows attackers to craft malicious XML input with external entity references, enabling arbitrary file read access on the server in the context of the application's running user privileges.

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 Adobe Campaign Classic versionLocate the version file or check the about page in the Adobe Campaign client console. Common paths include the installation directory or the version can be retrieved via the Administration > Configuration > Options menu in the client.Affected if The installed version is 18.10.5.8984 or earlier
-
Locate XML import or upload functionalitiesIdentify any features in Adobe Campaign that accept XML input, such as import workflows, data import, or API endpoints that process XML payloads. Check workflow activities and web applications that handle XML data.Affected if XML processing functionality exists and is accessible to users
-
Inspect XML parser configurationExamine the server configuration files (typically serverConf.xml or similar) for XML parser settings. Look for parameters related to external entity processing or DTD handling in the XML parser configuration.Affected if The XML parser is configured to allow external entity resolution or DTD processing
-
Test for XXE vulnerabilitySubmit a crafted XML payload with an external entity reference (such as <!DOCTYPE foo [<!ENTITY xxe SYSTEM "file:///etc/passwd">]>) to any XML input point in Adobe Campaign and observe if the content is returned in the response.Affected if The application parses the XML and returns content from external entity references
You are affected if Adobe Campaign Classic version is 18.10.5.8984 or earlier and XML processing features with external entity resolution are enabled

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 dataUpgrade Adobe Campaign Classic to a patched version beyond 18.10.5-8984, and ensure XML parsers are configured to disable external entity processing.
