# Exploit Title: SolarWinds Serv-U 15.4.2 HF1 - Directory Traversal
# Date: 2025-05-28
# Exploit Author: @ibrahimsql
# Exploit Author's github: https://github.com/ibrahimsql
# Vendor Homepage: https://www.solarwinds.com/serv-u-managed-file-transfer-server
# Software Link: https://www.solarwinds.com/serv-u-managed-file-transfer-server/registration
# Version: <= 15.4.2 HF1
# Tested on: Kali Linux 2024.1
# CVE: CVE-2024-28995
# Description:
# SolarWinds Serv-U was susceptible to a directory traversal vulnerability that would allow
# attackers to read sensitive files on the host machine. This exploit demonstrates multiple
# path traversal techniques to access Serv-U log files and other system files on both
# Windows and Linux systems.
