Mozilla Foundation Security Advisory 2013-43
Title: File input control has access to full path
Announced: May 14, 2013
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.
