If you are using a Webform file upload field, then your site could be vulnerable.They are taking advantage of the File Webform component's Upload button that, via AJAX, allows the user to upload a file before submitting the form.

Upon clicking the Upload button, the website default ajax functionality then displays the stored location of the file in plain sight almost instantly.

There is a patch to remove the ajax Upload button here: - This will prevent the instant upload of files to your server.2. Be sure to set a custom path for your file uploads. Anything other than leaving it blank will work. This will help prevent the attacker from guessing the upload path upon submitting the form.

You can also set your Upload destination to private, but that will prevent people receiving the link via email from opening a legitimate file without being logged into the site first - could be annoying to them.3. Clear out any old Webform submissions (Delete all Webform Upload files.

Problem:A website blew up on me (I think due to human error). This site was built quickly in 2 weeks and uses the module to collect academic references for incoming students for research programs. While the site was built quickly, I do use for example the Backup and Migrate module to routinely backup the website at least daily. But, the site got hosed, and there were 150+ webform submissions which I did not know if the client had successfully used default PDF mechanism to archive all the submissions to PDF I wanted to generate every single webform submission as a PDF and store it on the server, and email the client all these PDFs as insurance while we triage the site problems and possibly reset the webapp to an initial known state. Read on to see how I save all webform submissions as PDFs using contributed modules to automate the process.Initial Brainstorming and Design of Solution:As I mentioned the site is using Webform and Webform2PDF to create PDFs of submissions. Out of the box webform pdfs are built dynamically when a url is visited and streamed to the client; by initial design the Webform2PDF module does not store generated pdf files on the server.Being a regular contributed to Drupal StackExchange I’ve actually seen this question asked before, ” sorry, you can’t.”.As the reply to that post hints at, perhaps there is an automated solution Automating PDF Generation to Server DiskThis is my solution I created in about 2 hours for a client (including debugging and running it all, etc).

This is what I consider a proof-of-concept and by no means a fully polished product. In a nutshell:. I want to make a url link on a staff administrative dashboard to generate the PDFs.

When pressed this link should process a rule that fetches a listing of all webform submissions default PDF download URLs provided by the webform2pdf module. The generated list of links should in-turn be p rocessed by the (drupal) system and save the PDFs to disk.So here is what the client sees for these steps in the final product. They see an admin panel with a link to generate PDFs. Final pdf files sitting on server folder. They are given a default name from the webform2pdf module of WebformID and then Submission ID dot pdf. The Recipe. I created a Dashboard using the module.

This was a component released with the site originally to be used by staff. I added a custom content item to the Panel Content with a link for PDF generation at /generate-webform-submission-pdfs. This custom URL is connected to a Rule using the module.The Rules Link Event modules allows arbitrary internal site urls to be tied to be Actions Rules responds to.
