This is a joomla CMS , which can be identified if you have wappalyzer extension installed
|
||||
|
||||
So I ran diresarch but found nothing interesting
|
||||
|
||||
<img src="https://imgur.com/YFgXm3P.png"/>
|
||||
|
||||
I went to google for any exploits available for joomla and found one metasploit module
|
||||
|
||||
<img src="https://imgur.com/fdzAg6d.png"/>
|
||||
|
||||
<img src="https://imgur.com/HtUYNQP.png"/>
|
||||
|
||||
But this exploit didn't work
|
||||
|
||||
<img src="https://imgur.com/J50H507.png"/>
|
||||
|
||||
So searched again to find any exploits and came across sql injection for joomla
|
||||
|
||||
<img src="https://imgur.com/SQog8bV.png"/>
|
||||
|
||||
<img src="https://imgur.com/vUIXuid.png"/>
|
||||
|
||||
After sometime it came back with databases
|
||||
|
||||
<img src="https://imgur.com/SR1Stk2.png"/>
|
||||
|
||||
Now let's select `joomladb` database and see it's tables
|
||||
|
||||
<img src="https://imgur.com/BkNfAS3.png"/>
|
||||
|
||||
It will start to retrieve the tables from the database
|
||||
|
||||
<img src="https://imgur.com/s8J4HNL.png"/>
|
||||
|
||||
Now we are interested in `users` table
|
||||
|
||||
<img src="https://imgur.com/RupveiZ.png"/>
|
||||
|
||||
I tried to enumerate for columns in table but couldn't
|
||||
|
||||
<img src="https://imgur.com/DKQg78Q.png"/>
|
||||
|
||||
<img src="https://imgur.com/GufIaZn.png"/>
|
||||
|
||||
Then went with guessing the column name to be `name` and it returned an entry in the table so the next column could be password
|
||||
|
||||
<img src="https://imgur.com/StqdYa0.png"/>
|
||||
|
||||
```bash
|
||||
sqlmap -u "http://192.168.1.10/index.php?option=com_fields&view=fields&layout=modal&list[fullordering]=
|
||||
updatexml" --risk=3 --level=5 --random-agent --dbs -p 'list[fullordering]' -D 'joomladb' --tables -T '#__users' --columns -C name,password --dump --
|
||||
batch
|
||||
```
|
||||
|
||||
<img src="https://imgur.com/pyMvpna.png"/>
|
||||
|
||||
The hash looks like bcrypt so let's try cracking it with `john`
|
||||
|
||||
<img src="https://imgur.com/h9KexPf.png"/>
|
||||
|
||||
We can now login to joomla with `admin:snoopy`
|
||||
|
||||
<img src="https://imgur.com/h6BQaPV.png"/>
|
||||
|
||||
<img src="https://imgur.com/EvjnDus.png"/>
|
||||
|
||||
To get a reverse shell , go to `Extensions` -> `Templates`
|
||||
|
||||
<img src="https://i.imgur.com/bUfOKbm.png"/>
|
||||
|
||||
And edit the `error.php` file
|
||||
|
||||
<img src="https://i.imgur.com/5dZOiRe.png"/>
|
||||
|
||||
<img src="https://imgur.com/IN4pYCY.png"/>
|
||||
|
||||
Now you just need to to navigate to that file , `/templates/beez3/error.php`
|
||||
|
||||
But this didn't work let's try to add a simple command injection paramter
|
||||
|
||||
<img src="https://imgur.com/8SH0P9f.png"/>
|
||||
|
||||
<img src="https://imgur.com/Co3r6O7.png"/>
|
||||
|
||||
<img src="https://imgur.com/EKsnnm9.png"/>
|
||||
|
||||
Now we have a rce ,just need to get a reverse shell
|
||||
|
||||
<img src="https://imgur.com/dbaqemR.png"/>
|
||||
|
||||
We have a shell great ! , so now let's run linpeas
|
||||
|
||||
<img src="https://imgur.com/RF945CW.png"/>
|
||||
|
||||
Right off the bat it shows that it's using an old linux kernel so there is an exploit available
|
||||
|
||||
<img src="https://imgur.com/I32glok.png"/>
|
||||
|
||||
<img src="https://imgur.com/RF945CW.png"/>
|
||||
|
||||
Download and transfer the exploit to traget machine make sure to covert it to unix format using `dos2unix`
|
||||
|
||||
<img src="https://imgur.com/ICvKRJM.png"/>
|
||||
|
||||
After compiling and running ,it didn't worked
|
||||
|
||||
<img src="https://imgur.com/VJQztaz.png"/>
|
||||
|
||||
I searched again for an exploit and found one
|
||||
|
||||
<img src="https://i.imgur.com/vDYOiBJ.png"/>
|
||||
|
||||
<img src="https://imgur.com/Oelt3iT.png"/>
|
||||
|
||||
After running it crashed : |
|
||||
|
||||
<img src="https://imgur.com/FznhS1t.png"/>
|
||||
|
||||
Then found another exploit
|
||||
|
||||
<img src="https://imgur.com/viESMC3.png"/>
|
||||
|
||||
<img src="https://imgur.com/F6avcw6.png"/>
|
||||
|
||||
<img src="https://imgur.com/hIRnf9T.png"/>
|
||||
|
||||
<img src="https://imgur.com/ADVGVhd.png"/>
|
||||
|
||||
We need to just run `compile.sh` after that run the binary `doubleput`
|
