## Drupal

### Username enumeration

#### Register

In _/user/register_ just try to create a username and if the name is already taken it will be notified:

![](<../../.gitbook/assets/image (254).png>)

#### Request new password

If you request a new password for an existing username:

![](<../../.gitbook/assets/image (255).png>)

If you request a new password for a non-existent username:

![](<../../.gitbook/assets/image (256).png>)

### Number of users enumeration

Accessing _/user/\<number>_ you can see the number of existing users, in this case is 2 as _/users/3_ returns a not found error:

![](<../../.gitbook/assets/image (257).png>)

![](<../../.gitbook/assets/image (227) (1) (1) (1).png>)

### Hidden pages enumeration

**Fuzz `/node/$` where `$` is a number** (from 1 to 500 for example).\
You could find **hidden pages** (test, dev) which are not referenced by the search engines.

#### Installed modules info

```bash
#From https://twitter.com/intigriti/status/1439192489093644292/photo/1
#Get info on installed modules
curl https://example.com/config/sync/core.extension.yml
curl https://example.com/core/core.services.yml

# Download content from files exposed in the previous step
curl https://example.com/config/sync/swiftmailer.transport.yml
```

### Code execution inside Drupal with admin creds

You need the **plugin php to be installed** (check it accessing to _/modules/php_ and if it returns a **403** then, **exists**, if **not found**, then the **plugin php isn't installed**)

Go to _Modules_ -> (**Check**) _PHP Filter_ -> _Save configuration_

![](<../../.gitbook/assets/image (252).png>)

Then click on _Add content_ -> Select _Basic Page_ or _Article -_> Write _php shellcode on the body_ -> Select _PHP code_ in _Text format_ -> Select _Preview_

![](<../../.gitbook/assets/image (253).png>)

### Post Exploitation

#### Read settings.php

```
find / -name settings.php -exec grep "drupal_hash_salt\|'database'\|'username'\|'password'\|'host'\|'port'\|'driver'\|'prefix'" {} \; 2>/dev/null
```

#### Dump users from DB

```
mysql -u drupaluser --password='2r9u8hu23t532erew' -e 'use drupal; select * from users'
```
