Re: GET or POST

2014-08-09 Thread Steve Thomas
Thanks Andras, I decided to do what you suggested with the condition. It 
works. If a manager of one company is editing one of their employees and 
decides to change the (id) in the address bar and the (id) belongs to an 
employee of a different company, a blank edit form will appear. If they 
fill out the form it simply adds another employee to their company roster.
I'm still amazed there isn't something in cakephp that solves it with a 
post.

Thanks for youe help.

 So when changing the id in the url the application still only allows fetch

 The same applies for delete, just check before if current user has access 
 to the record to be deleted…

 If you need to hide id, then one option is to use uuid() as primary key.

 Thanks Mark,
 I am using ACL. So for example, if a role such as a manager can list all 
 the employees of that company, it also adds the Action links (add) (edit) 
 (delete). If this manager clicks to edit one of the employee (users), this 
 is sent to the EDIT view via GET with the user id in the address bar 
 - controller/method/id. All the manager would have to do is change the id 
 in the address bar to access another user. Possibly a user from a different 
 company which they shouldn't be able to access.  
 It's generally not acceptable programming to send account id via GET 
 because of this security breach. It should always be sent POST. However, 
 the EDIT form submits to its self and therefore conflicts with other posts.
 I was hoping this is such a basic and common flaw that there would be an 
 easy fix.
 I hope that cleared up what I'm trying to accomplish. 
 Another example is the DELETE link on the same Action with EDIT and ADD 
 uses postLink() to avoid the id being sent via GET in the address bar. 
 However, the delete page doesn't have any other POST or self submissions 
 and no conflicts.

Re: GET or POST

2014-08-09 Thread Andras Kende
Stave,

To keep things simple as possible I would :
Edit with a changed id should not save as new record, there is add() for that 
action..
Manipulating the id in the url should either redirect to index with a flash 
warning message or throw an error..

You could add a condition like

'conditions' = array(
'Employee.company_id' = $this-Auth-user('company_id')
)

So when changing the id in the url the application still only allows fetch data 
which belongs to the same company..

The same applies for delete, just check before if current user has access to 
the record to be deleted...

If you need to hide id, then one option is to use uuid() as primary key.

Re: Using GET not POST returns empty $this-data

2011-09-06 Thread WebbedIT
First rule of security . never trust the user!  You really need to
watch Pierre Spring's (http://twitter.com/#!/shvi) CakeFest talk on
security when it is uploaded, it will scare the be-jeesus out of you!
Keep an eye out for that on tv.cakephp.org when @phpNut recovers from
his flight home, edits the talks and uploads them.

The problem is, the only way a user communicates with your app is via
HTTP requests and your server does not know if that request has come
from an evil hacker or an angelic genuine user.

Therefore you must ensure that any data posted to your app is only
ever sent from a form you created, that is served from within your
app*.  Same thing with delete requests, you should only ever accept
these from POST - how easy is it to type '/users/delete/1', '/users/
delete/2', 'users/delete/3' etc..

With GET requests anyone can type variable names and values direct
into the parameters string and add or update any field for any record
in your database without ever being on your site.  Ok, you can do some
authenticate and authorisation checks after recieving the request to
see if they own the record, but what if the user has managed to
compromise a user's account? (again Pierre Spring's talk will show how
easy this is if not protected with simple but effective methods that
CakePHP provide if used correctly).

* The only time you should accept POST requests from an external
server is if you've written an API, but then you need to operate on
HTTPS and have Keys and Tokens etc. to authorise requests.

Re: Using GET not POST returns empty $this-data

2011-09-05 Thread WebbedIT
Thomas,

It is a VERY bad idea to accept data via GET that you are going to
write into your database.  Please do not do it, you should only accept
POST data and as such your function should go back to the standard:

if(!empty($this-data)) {

} else {

}

CakePHP has built in security and takes anything submitted via POST
and transfers it into $this-data for you so the above code
essentially says only save data if submitted by a form.  If you use
the form helper it creates the data array in exactly the right format
so you can simply call $this-Model-save();  Ideally you should also
enable the security component which will insert a token into your
forms too ensure your forms are being submitted from your site and not
being tampered with before submission.

The main thing to learn is, if you are going to use CakePHP, stick to
it's conventions.  Those conventions were created by a bunch of very
clever people, as soon as you try doing things differently you are
making your life sooo much harder and most probably weakening various
aspects of your application.

I am new to this.  Does this mean that I go to the controller and
change the

$this-data

to

$this-params['url']

?

So my edit post would be


function add() {
if (!empty($this-params['url'])) {
$this-Post-create();
if ($this-Post-save($this-params['url'])) {
$this-Session-setFlash(__('The post has been 
saved', true));
$this-redirect(array('action' = 'index'));
} else {
$this-Session-setFlash(__('The post could not 
be saved. Please,
try again.', true));
}
}
$users = $this-Post-User-find('list');
$this-set(compact('users'));
}

?  I'll go and try it...

I found that just created a post when I clicked Add without giving a
screen to create it. :(

Using GET not POST returns empty $this-data

2011-09-02 Thread Thomas
I am trying to make a very simple link up between an android app 
(appinventor) and a standard cake app.  I have created the blog tutorial and 
it all works great.  I can make my app link to another web site with a URL 
and return XML (a simple API request) so I know it works, I just want to do 
the same with cake.

I can't work out the syntax of a the POST to send with appinventor, but I 
can make the 'add' form use GET with 

*echo $this-Form-create('Post', array('type' = 'get'));*

When I use this form I see the correct parameters in the URL, but *
$this-data* appears empty and nothing is saved - the add page just comes 
straight back.

I have scoured this group, the Bakery and the internet for an hour now and 
am demoralised. I know it must be something simple in the *
posts_controller.php* but I can't find it.

With GET request your data goes to $this-params['url']
