With resep kue enak dan. Our research showed that the main requirements for successful RCE attacks on unmarshalling libraries are that: 1) The library invokes methods on user-controlled types such as non-default constructors, setters, deserialization callbacks, destructors, etc. Researchers have found complex object graphs which, when deserialized, can lead to remote code execution in most Java software. The next example is a denial-of-service attack against any Java application that allows deserialization. Certain versions of the Jackson library (jackson-databind) allow unauthenticated remote code execution (RCE), exploitable by maliciously crafted JSON input.
