CWE: CWE-611 \u2014 Improper Restriction of XML External Entity Reference
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.

Code:
	public String getMemento() {
		String collectData = ""; //$NON-NLS-1$

		DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
		DocumentBuilder docBuilder = null;
		try {
			docBuilder = dfactory.newDocumentBuilder();
			Document doc = docBuilder.newDocument();

			Element rootElement = doc.createElement("whileSteppingData"); //$NON-NLS-1$
			rootElement.setAttribute("whileSteppingCount", Integer.toString(fStepCount)); //$NON-NLS-1$
			rootElement.setAttribute("subActionNames", fSubActionNames); //$NON-NLS-1$

			doc.appendChild(rootElement);

			ByteArrayOutputStream s = new ByteArrayOutputStream();

			TransformerFactory factory = TransformerFactory.newInstance();
			Transformer transformer = factory.newTransformer();
			transformer.setOutputProperty(OutputKeys.METHOD, "xml"); //$NON-NLS-1$
			transformer.setOutputProperty(OutputKeys.INDENT, "yes"); //$NON-NLS-1$

			DOMSource source = new DOMSource(doc);
			StreamResult outputTarget = new StreamResult(s);
			transformer.transform(source, outputTarget);

			collectData = s.toString("UTF8"); //$NON-NLS-1$

		} catch (Exception e) {
			GdbPlugin.log(e);
