我在这个博客上寻找了类似的帖子,但是没有找到我的问题的答案,所以我决定寻求帮助。
我用Java编写了这个简单的函数:
public void open(InputStream stream) throws FoliumFatalException {
try {
InputSource is = new InputSource(stream);
DocumentBuilderFactory dfact = DocumentBuilderFactory.newInstance();
// /* OWASP: inhibit access to External Entities */
dfact.setAttribute(XMLConstants.ACCESS_EXTERNAL_DTD, "");
dfact.setAttribute(XMLConstants.ACCESS_EXTERNAL_SCHEMA, "");
_doc = dfact.newDocumentBuilder().parse(is);
} catch (Throwable t) {
_logger.error(t, t);
throw new FoliumFatalException("ENG-0017", "Errore di parsing su stream", t);
}
}
我的目标是应用OWASP标准,如此处所述,但我收到以下错误:
java.lang.IllegalArgumentException: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.
java.lang.IllegalArgumentException: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.
