This document describes how to use and manage the SonicWALL SSL VPN File Shares Applet feature.

While these steps are specific to Dell SonicWALL Virtual Office, you can re-use this same methodology for most login portals with CSRF tokens.SonicWALL SSL VPN File Shares Applet Document Scope Given this constraint, this is probably something you want to run overnight with a long delay between attempts. Instead of the CRSF token being present, it is replaced with a redirect to dynLoginFull.html. If you try too quickly, the application will likely start blocking you. This way the extracted tokens sync up properly, and you avoid locking up the application. It is also recommended to go to Request Engine and set вЂњ Number of ThreadsвЂќ to 1 as well as set a long delay. You can then sort on the value of this field to identify successful logins.

The reason we do this is because both an invalid attempt and a valid attempt will return an HTTP 200 OK, however only successful attempts will set the вЂњ sessIdStrвЂќ variable in JavaScript.

Select the вЂњ End at delimiterвЂќ radio button.

Input sessIdStr = вЂњ into the input field.

Go to Intruder -> Options -> Grep вЂ“ Extract.

If you need to brush up, consider reading How to Burp Good.

IвЂ™m going to assume you know how to perform a normal password spray in Burp Suite Intruder, so this section will just address the unique parts of this. Step 3: Run the Burp Suite Intruder attack This id value will then be placed in any вЂњidвЂќ field it finds. It should then parse out the value present in the hidden вЂњidвЂќ field. If you did the steps properly, anytime you make a request, Burp will first make a request to auth.html.

Leave everything else default and click вЂњ OKвЂњ.

Select вЂњ Run A MacroвЂќ from the drop-down.

Input Sessions -> Session Handling Rules.

Select the вЂњ Start after expressionвЂќ radio button.

Make sure the вЂњ Define start and endвЂќ checkbox is checked.

Click вЂњ AddвЂќ next to the вЂњ Custom Parameter locations in responseвЂќ window.

In the Macro Recorder window, select a request to auth.html.

Macros can be created under Project Options -> Sessions -> Macros.

Here is what we need to do to make the attack work in Burp Suite Intruder: Step 1: Create a Macro Why does this matter to us? Well, if we do not have the right вЂњidвЂќ parameter in our POST request to auth.cgi, we will not receive a successful authentication regardless of whether or not we supplied a valid credential pair. Every time a user visits sslvpnLogin.html or auth.html a new, unique вЂњidвЂќ parameter is placed in a hidden field, which is sent in the POST request. The ID parameter is effectively acting as a CSRF token. I never set that, yet here it is in my request. Id=90&domain=DOMAIN&uName=USER&pass=PASSWORD&SslvpnLoginPage=1&digest=Дo you see it? The вЂњidвЂќ parameter.

Typically what I will do when I see something like this is I will perform a password spray against it based on usernames I have collected from Open Source Intelligence (OSINT) during the reconnaissance phase of my pentest. Today I came across a Dell SonicWALL virtual office login page.
