|Mozilla Firefox 188.8.131.52, 2.0.x before 184.108.40.206, Mozilla Suite 1.7.13,
Mozilla SeaMonkey 1.0.2 and other versions before 1.1.5, and Netscape
8.1 and earlier allow user-assisted remote attackers to read arbitrary
files by tricking a user into typing the characters of the target

those characters to be inserted into a file upload input control,
which can then upload the file when the user submits the form.
