j@m3s
|

jm3s (Not a valid username)

wpdiscuz:7.0.4
|

|

There's an exploit for wpdiscuz

But this module wasn't getting imported so I went with manual exploitation , there are some poc on youtube so I followed that.
|

|
Go to any blog post

Stabilize the shell with `python3 -c 'import pty;pty.spawn("/bin/bash")';`
|

We can see that it's creating an archive using a wild card so here we can exploit it through wildcard.
|
||||||
|
|
||||||
|
We can also find creds for mysql
|
||||||
|
|
||||||
|
```
|
||||||
|
/** MySQL database username */
|
||||||
|
define('DB_USER', 'root');
|
||||||
|
|
||||||
|
/** MySQL database password */
|
||||||
|
define('DB_PASSWORD', 'sup3r_s3cr3t');
|
||||||
|
|
||||||
|
/** MySQL hostname */
|
||||||
|
define('DB_HOST', 'localhost');
|
||||||
|
|
||||||
|
/** Database Charset to use in creating database tables. */
|
||||||
|
define('DB_CHARSET', 'utf8');
|
||||||
|
|
||||||
|
/** The Database Collate type. Don't change this if in doubt. */
|
||||||
|
define('DB_COLLATE', '');
|
||||||
|
```

I tried cracking this password but failed. Later found a creds file in `/opt` , didn't understood what type of text was that but tried that password for james user it didn't work as well
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
After a lot of struggling , trying password , cracking the hash nothing seemed to work. I read the `/etc/passwd` file , there was a user name `vagrant` , tried the password for vagrant : vagrant and got switched to him
|
||||||
|
|

|
||||||
|
|
||||||
|
Now here I don't know if this was intended or forgot to remove this as there was a cronjob running which could have been exploited through wildcard technique if we could found jame's password but I didn't find it anywhere on the box so just have some doubts here. Anyways this was the root for this box.
