我对sonarqube运行了我的java代码，我得到了禁用XML外部实体（XXE）处理作为漏洞。我花了一些时间在谷歌上解决这个问题。我一直在尝试很多方法，但没有什么对我有用。我不知道我错过了什么
我的代码：
final DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
docFactory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
docFactory.setFeature(XMLInputFactory.IS_SUPPORTING_EXTERNAL_ENTITIES, false);
docFactory.setFeature(XMLInputFactory.SUPPORT_DTD, false);
docFactory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
docFactory.setFeature("http://xml.org/sax/features/external-general-entities", false);
docFactory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
docFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
final DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
final Document doc = docBuilder.parse(filepath);
我用的是java1.8谢谢
我最终添加了以下所有属性，以避免Sonar抱怨此漏洞：
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
//REDHAT
//https://www.blackhat.com/docs/us-15/materials/us-15-Wang-FileCry-The-New-Age-Of-XXE-java-wp.pdf
factory.setAttribute(XMLConstants.FEATURE_SECURE_PROCESSING, true);
factory.setAttribute(XMLConstants.ACCESS_EXTERNAL_DTD, "");
factory.setAttribute(XMLConstants.ACCESS_EXTERNAL_SCHEMA, "");
//OWASP
//https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html
factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
// Disable external DTDs as well
factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
// and these as well, per Timothy Morgan's 2014 paper: "XML Schema, DTD, and Entity Attacks"
factory.setXIncludeAware(false);
factory.setExpandEntityReferences(false);
DocumentBuilder builder = factory.newDocumentBuilder();
Java9解决方案：
对我来说，将DocumentBuilderFactory. newInstance（）更改为DocumentBuilderFactory.newDefaultInstance（）足以消除此警告。
只需设置这两个属性就足够了：
factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
