Subject [jira] [Created] (AXIS2-5877) ConvertUtils.java:225 (XML External Entity Injection)

             Summary: ConvertUtils.java:225 (XML External Entity Injection)
                 Key: AXIS2-5877
                 URL: https://issues.apache.org/jira/browse/AXIS2-5877
             Project: Axis2
          Issue Type: Bug
          Components: jaxws
    Affects Versions: 1.7.6
            Reporter: Donald Kwakkel
            Priority: Critical


XML parser configured in ConvertUtils.java:225 does not prevent nor limit external entities
resolution. This can expose the parser to an XML External Entities attack.

Proposed fix: Enable where TransformerFactory is used always the secure processing feature:


{code:java}
	public static TransformerFactory createTransformerFactory() {
		TransformerFactory factory = TransformerFactory.newInstance();
		try {
			factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
		}
		catch (TransformerConfigurationException e) {
			throw new IllegalStateException(e);
		}
		return factory;
	}
{code}
