Open Microscopy Environment

I'm having the strangest problem.

I'm migrating from an old version to new OMERO, and have some customizations. The old version is working.

On my new version, I have some pages that are using the web public user. I have them in omero.web.public.url_filter. When I open to these pages on a new tab or refresh- they work without a login. When I refer from one page to another using POST forms I get

Forbidden (403)
CSRF Error. You don't have permission to access this page on this server.

I can then refresh that same page and it appears. I'm assuming the CSRF isn't following through the link but is being recreated via the public user on new page/refresh.

In the logs, I have this for the broken pages:

Code: Select all

What am I missing?

Hi

Any 'unsafe' HTTP operations, such as POST always require a valid CSRF token. http://www.openmicroscopy.org/site/supp ... /CSRF.html

Even when using a web public user? This previously wasn't the case with OEMRO version 4.4?

These pages are listed in omero.web.public.url_filter

That's correct. CSRF is a potential security vulnerability which was fixed in OMERO 5: http://www.openmicroscopy.org/site/prod ... 4-SV3-csrf

Would it be possible to get an example of a html form that goes from one public url page to another public url page?

Thanks,

Hi,

You need to include

Code: Select all

{% csrf_token %}

in your form. See https://docs.djangoproject.com/en/1.8/ref/csrf/
