Talk:PDF Attack Filter for Java EE
Should this page be in the Countermeasures category and have a link off of https://www.owasp.org/index.php/Category:Countermeasure?
Absolutely - fixed
It seems there's a much simpler approach to preventing this vulnerability on the server-side that Adobe supposedly released back on January 9th (in addition to their browser plug-in patches).
1. Simply configure server to change MIME type header to "application/octet-stream" for pdf exetensions OR 2. Simply add a Content-Disposition Header with a value of "attachment; filename=yourfile.pdf"
There's a 3rd option with a custom code solution, but it seems like it would still require the 1st solution to truly work so I don't think it’s a viable solution.
All of the details on how to configure this on a per-server basis (at least IIS 6.0, Apache 2.2.3) can be found here:
