Security Vulnerability - Action Required: XXE vulnerability in the newest version of the JFoenix

[Crispy-fried-chicken]

I think your project may be vulnerable to Improper Restriction of XML External Entity Reference. It shares similarities to a recent CVE disclosure CVE-2021-3869 in the project stanfordnlp/CoreNLP. The vulnerable methods are as follows:

1. com.jfoenix.svg.SVGGlyphLoader.loadGlyphsFont(URL url) in the file jfoenix/src/main/java/com/jfoenix/svg/SVGGlyphLoader.java
2. com.jfoenix.svg.SVGGlyphLoader.loadGlyphsFont(InputStream stream, String keyPrefix) in the file jfoenix/src/main/java/com/jfoenix/svg/SVGGlyphLoader.java

The source vulnerability information is as follows:

Vulnerability Detail:
CVE Identifier: CVE-2021-3869
Description: corenlp is vulnerable to Improper Restriction of XML External Entity Reference
Reference:https://nvd.nist.gov/vuln/detail/CVE-2021-3869
Patch: stanfordnlp/CoreNLP@5d83f1e

Vulnerability Description:
This vulnerability occurs because of the Improper Restriction of XML External Entity Reference. Given that the XML schema files which is compromised by a hacker, the victim conducts regular process may result in an XML External Entity (XXE) Injection attack.

Recommended Actions:
The corresponding fixes are similar to CVE-2021-3869 to some extent. I have provided the following fixes by applying several patching statements, ensuring that the external entities and DTDs are not loaded when parsing and processing XML documents using the document builder. You can call the function safeDocumentBuilderFactory I defined below instead of directly calling DocumentBuilderFactory.newInstance() to create a DocumentBuilderFactory object to avoid XXE attacks.

  public static DocumentBuilderFactory safeDocumentBuilderFactory() {
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    try {
      dbf.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
      dbf.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
      dbf.setFeature("http://xml.org/sax/features/external-general-entities", false);
      dbf.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
      dbf.setFeature("http://apache.org/xml/features/dom/create-entity-ref-nodes", false);
      dbf.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
    } catch (ParserConfigurationException e) {
      log.warn(e);
    }
    return dbf;
  }
