The summary of the given text is as follows: The environment consists of a Kali system as the attacking machine, a CentOS machine as the intermediary, and a target machine. The target machine's IP is 192.168.1.4:8983, the local machine's IP is 192.168.1.2, and the attacking machine's IP is 192.168.91.131. The attack involves opening the target machine's environment and making a DNS request to a specific domain. By modifying the domain, the attacker gains access to the target machine and executes commands. The attacker then uses JNDIExploit-1.2 to input a command and opens a port listener on the attacking machine. Finally, the attacker constructs a command in the hackbar and executes it, resulting in a shell being returned to the attacker.
