Hello, I'm trying to login to a login form with JS app that does not seem to have an id:

<form _ngcontent-c1="" class="loginform ng-pristine ng-invalid ng-touched" novalidate="">

    <img _ngcontent-c1="" alt="" class="loginform-logo" src="assets/img/logo.svg">


    <label _ngcontent-c1="" class="loginform-label icon-user" for="username">Username</label>
    <input _ngcontent-c1="" class="loginform-input ng-pristine ng-invalid ng-touched" id="username" name="username" required="" type="text">
    <div _ngcontent-c1="" class="input-error" hidden="">
        Username is required

    <label _ngcontent-c1="" class="loginform-label icon-lock" for="password">Password</label>
    <input _ngcontent-c1="" class="loginform-input ng-pristine ng-invalid ng-touched" id="password" name="password" required="" type="password">
    <div _ngcontent-c1="" class="input-error" hidden="">
        Password is required

    <button _ngcontent-c1="" class="loginform-btn icon-triangle-right btn btn-main" type="submit" disabled="">Login

  1. When I use a ruby form I get the response:

[-] [utilities#exception_jail:428] Session: [Watir::Exception::UnknownObjectException] unable to locate element, using {:id=>"login", :tag_name=>"form"}

  1. with the autologin script I get the response:

[-] [utilities#exception_jail:428] Session: [Arachni::Session::Error::FormNotFound] Login form could not be found with: {:url=>"", :inputs=>{"username"=>"myname", "password"=>"mypassword"}}

the script:

browser.goto ''

form = browser.form( id: 'login' )
form.text_field( name: 'username' ).set 'myname'
form.text_field( name:'password' ).set 'mypassword'


framework.options.session.check_url = browser.url
framework.options.session.check_pattern = /logout/
  1. arachni --checks=xss_dom --plugin= --output-debug --plugin=login_script:script=login.rb

  2. arachni --checks=xss_dom --plugin=autologin:url=,parameters='username=myname&pass...' --output-debug

I would appreciate your suggestion..

Maybe an example ruby script if you have.. This is a spring boot app with csrf token..

Kind regards,

    Sounds like it could be a PhantomJS issue, it may not support the webapp but there's not much I can do about it.
    The new engine will use modern engines (Chrome and Firefox) so these issues will be resolved once it's released, although it'll be a while.

    Until then, I wouldn't mind having a look at that website if that's possible.

    Also, sorry for the very late response, I've been hard at work for the new engine.
