upload.php可以文件上传

测试发现不准上传php文件，但可以上传phtml文件

用phtml上传一个一句话马，然后弹个shell

但是我在提权root时候遇到了问题，没有什么敏感文件，也没有定时任务，也没有suid提权，也没有什么root权限脚本...

然后回到这个bash上，一般bash都是www-data,为什么这次是bash-5

搜索一番知道home目录下.bash_profile .bashrc这两个文件被删了就会出现这种情况

但是修复也没有权限

然后尝试用bash -p就拿到了root权限

bash-5.1$ bash -p
bash -p
id
uid=33(www-data) gid=33(www-data) euid=0(root) egid=0(root) groups=0(root),33(www-data)
whoami
root
