#### Software description:
# Save time on FTP/SFTP updates! Plan your uploads and automate the workflow. 
# Schedule and automate file transfers with a centralized console. Let your 
# computer move or synchronize information securely between home and office 
# automatically according to the schedule!
#
#### Exploit information:
# There was an error when sending a response to the PASV command. 
# Fortunately, these errors lead to buffer overflows. 
# This exploit is unstable. It should only be used as a POC.
# I tried several times on various systems,  
# the buffer sometimes changed.
# 
### Some Conditions:
# This POC is using "the most selling feature" Automated FTP Request.
# So this POC, I use Auto Download with / as the Source Files.
# Scheduler Settings also set to Repetitive.
# Make sure to run the program first before this POC.
# 
#### Other information:
# It's a part of "Death of an FTP Client" :)
# For more information, loot at here:
