获取webshell

这里的版本是有LFI漏洞，但是有问题它只能读取一行，我看了一篇关于这个的文章：https://www.leavesongs.com/PENETRATION/jenkins-cve-2024-23897.html

我得到的结论是我们被匿名关闭了，并且加了权限设置，所以我们如果要突破必须进行密码读取，这里我找到了密码的明文路径：/secrets/initialAdminPassword，用户admin

我后面直接给自己加ssh省得调终端

提权

需要进行端口转发

无密码登录，OK

到这里结束了本来我以为我写个java脚步运行就成功了，但是脚步失败还是最朴素的方案吧

好了靶机到这里就结束了，整体来说是一个easy的靶机后面，前面可能费点劲
