             Summary: ValidateXMLFile.java:55 (XML External Entity Injection)
                 Key: AXIS2-5878
                 URL: https://issues.apache.org/jira/browse/AXIS2-5878
             Project: Axis2
          Issue Type: Bug
          Components: jaxws
    Affects Versions: 1.7.6
            Reporter: Donald Kwakkel
            Priority: Critical


XML parser configured in ValidateXMLFile.java:55 does not prevent nor limit external entities resolution. This can expose the parser to an XML External Entities attack.

Proposed solution: Always disable external entities when creating a DocumentBuilderFactory:
{code:java}
	public static DocumentBuilderFactory createDocumentBuilderFactory() {
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		factory.setNamespaceAware(true);
			try {
				factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
				factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
			}
			catch (ParserConfigurationException e) {
				throw new IllegalStateException(e);
			}
		return factory;
	}
{code}
