Article Describes Exploitation of Fastjson Deserialization RCE Vulnerability

The article describes the reproduction of a Remote Code Execution (RCE) vulnerability related to fastjson deserialization. The process involves several technical steps. First, a class containing malicious code must be written on the attacker's machine and compiled into a class file. This class includes the commands to be executed. Next, an RMI service must be deployed on the attacker's machine using a jar file. Finally, a payload request is sent to attack the RMI service of the target machine. The technical details include the use of malicious Java classes and RMI services to exploit the vulnerability.
