How to Fix CVE-2017-18197

To remediate this vulnerability, upgrade all affected Mxgraph dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

mxgraph fixed: 3.7.6 
npm install mxgraph@3.7.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls mxgraph

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-18197, inspect your project dependencies using npm:

npm ls mxgraph

Analyze the terminal output to locate any version of Mxgraph in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.7.6), your application is affected.

Note: The npm ls mxgraph command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In Mxgraph, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In `mxGraphViewImageReader.java` in mxGraph before 3.7.6, the `SAXParserFactory` instance in `convert()` is missing flags to prevent XML External Entity (XXE) attacks, as demonstrated by `/ServerView`.
