Mozilla Foundation Security Advisory 2013-43

Title: File input control has access to full path
Impact: Moderate
Announced: May 14, 2013
Reporter: moz_bug_r_a4
Products: Firefox

Fixed in: Firefox 21.0


Mozilla security researcher moz_bug_r_a4 reported a mechanism to exploit the <input> control when set to the file type in order to get the full path. This can lead to information leakage and could be combined with other exploits to target attacks on the local file system.
