One implementation is implemented using the Jaxb2Marshaller class, which naturally implements two global interfaces, it is used for Bidirectional parsing of XML and Object. The XML file can be a DOM file, an input/output stream, or a SAX handler.Sp

attacker sends an external entity in an XML message to an application and parses it using an XML parser.
This vulnerability has many different types and behaviors because it may occur in different types of technology-because of the different types of XML parsers. In this case, happily, each parser has different functions and "characteristics".
Before we get started, let's take a look at the most common types of X
About blind XXE
For Xxe, I have shared it internally a long time ago. I personally think there is not much fun about the vulnerabilities themselves, mainly because: the diversity of processing URIs in different languages and some features of different XML parser in parsing XML.
Before the popularization of blind Xxe, we assume that you have mastered

Analysis of Different Types of DTD/XXE attacks
When evaluating the security of XML-based services, you cannot forget the DTD-based attacks, such as XML external entity injection attacks (XXE ).
In this article, we will provide a comprehensive list of attacks against different types of DTD.
Attacks are classified as follows:

As you all know, many web and mobile applications rely on client-server Web communication interaction services. In Web services such as soap and restful, the most common data formats are XML and JSON. When a Web service is transferred using either XML or one of the JSON, the server may receive data formats that the developer did not anticipate. If the XML parser on the server is not well configured, the terminal in the JSON transmission may suffer a XXe
