3. java反编译

获取到secret Sup3rS3cur3Dr0it

域名 adroit.local

用户名 zeus 域名 god.thunder.olympus

添加一个域名 adroit.local

尝试运行一下jar包

这里我用jdk8运行不了 ，切换到jdk11可以运行

提示输入账户密码 挨个测试即可

┌──(root㉿kali)-[/home/kali/hmv/Adroit]
└─# java -jar adroitclient.jar
Enter the username :
zeus
Enter the password :
Sup3rS3cur3Dr0it
Wrong username or password   ┌──(root㉿kali)-[/home/kali/hmv/Adroit]
└─# java -jar adroitclient.jar
Enter the username :
zeus
Enter the password :
god.thunder.olympus
Options [ post | get ] :
get
Enter the phrase identifier :
1

god.thunder.olympus 就是密码

4. sql注入

获取到了账户密码 writer:l4A+n+p+xSxDcYCl0mgxKr015+OEC3aOfdrWafSqwpY=
但是密码是加密的

但是加密的

5. 解密密码

解密的代码可以在jar包反编译中发现

密钥上面获取到了是 Sup3rS3cur3Dr0it
但是注意这里需要将0换成O
所以正确的密钥是 Sup3rS3cur3DrOit

参考 Mikannse的wp对这个进行解密

获取到密码是 just.write.my.ideas

6. 提权

利用账户密码登录

writer ： just.write.my.ideas

我觉得这个靶场不算难。难点只是在分析java代码那里，不过我看不懂java
