CVE-2019-14678
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 · uneditedSAS XML Mapper 9.45 has an XML External Entity (XXE) vulnerability that can be leveraged by malicious attackers in multiple ways. Examples are Local File Reading, Out Of Band File Exfiltration, Server Side Request Forgery, and/or Potential Denial of Service attacks. This vulnerability also affects the XMLV2 LIBNAME engine when the AUTOMAP option is used.
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 confidenceSAS XML Mapper 9.45 contains an XML External Entity (XXE) vulnerability in its XML parser. Malicious XML documents with crafted external entity references allow attackers to read local files from the server, perform Server Side Request Forgery (SSRF), exfiltrate data out-of-band, or cause Denial of Service. The vulnerability also impacts the XMLV2 LIBNAME engine when the AUTOMAP option is enabled.

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 SAS XML Mapper versionLocate and inspect the installed SAS XML Mapper version on the systemAffected if The installed version is exactly 9.45 (SAS XML Mapper)
-
Identify SAS Base versionLocate and inspect the installed SAS Base version on the systemAffected if The installed version is SAS Base 9.4 (any subversion)
-
Determine if XMLV2 LIBNAME engine is in useReview SAS configurations and code for references to the XMLV2 LIBNAME engineAffected if XMLV2 LIBNAME engine is actively used to process XML data
-
Check if AUTOMAP option is enabledInspect SAS XMLV2 LIBNAME engine configurations for the AUTOMAP option settingAffected if AUTOMAP option is enabled for the XMLV2 LIBNAME engine
You are affected if you use SAS XML Mapper version 9.45, or if you use SAS Base 9.4 with the XMLV2 LIBNAME engine and the AUTOMAP option is 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 dataApply vendor patches immediately when available. As immediate workarounds, disable the XMLV2 LIBNAME engine AUTOMAP option, implement strict XML input validation/sanitization to reject entity declarations, and consider deploying a WAF with XXE detection rules.
