Fortra GoAnywhere MFT 7.4.1 – Authentication Bypass

# 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.
