Another use method after InvokerTransformer is banned
CommonsCollections3 In CC1 and CC6, we finally called the calculator through Runtime.exec. From CC3, we will introduce a method to play the calculator without using Runtime, which is the dynamic class loading and dynamic class often mentioned in Java. Loading allows us to load a malicious class through a path. If the malicious class has […]
