访问log路径

WAF: Access Denied for this Host.



尝试ip伪造



任意文件读取文件



发现了一个

用户

clumsyadmin:x:1000:1000::/home/clumsyadmin:/bin/sh

再访问其他接口看看

update接口发现他会提示我用户不正确 试着填上刚刚发现的用户



发现成功



尝试命令注入



发现成功

已经可以rce了咋反弹shell我就不说了

拿到local.txt的用户flag之后我们就要开始提权了

发现了一个很有意思的事情

不管是wget 下来的文件文件所属者尽然都是root 导致我们chmod 不了 也就执行不了我们从kali下载下来的自动脚本

看来得想想其他办法了

这难不到我们 我们直接cp 一下文件复制出来的文件就是咱们自己所属的了



运行之后发现这个wget果然有点小问题 是suid权限的



直接suid提权了



提权成功

too easy 算下来1小时左右结束战斗 非常常规了个人感觉这个靶场
