CVE-2024-5806 is an improper authentication vulnerability in the SFTP module of Progress MOVEit Transfer that allows authentication bypass in affected versions. The issue affects MOVEit Transfer 2023.0.0 through before 2023.0.11, 2023.1.0 through before 2023.1.6, and 2024.0.0 through before 2024.0.2. Supporting content indicates the flaw is in SSH public key authentication handling within the SFTP service, where an attacker can abuse malformed or attacker-controlled input during authentication to impersonate a valid user without presenting legitimate credentials. Multiple sources in the content state exploitation may require only knowledge of a valid username, and describe indicators such as empty public key fingerprints, certificate store access failures, and path-based manipulation during key handling. Public proof-of-concept exploit code was released in June 2024, and the vulnerability has been reported as exploited in the wild.

This repository contains a single exploit script (progress-moveit_cve-2024-5806.py) targeting Progress MOVEit Transfer's SFTP authentication mechanism (CVE-2024-5806). The exploit leverages a log poisoning technique: it injects attacker-controlled SSH key data into a MOVEit Transfer log file via a crafted POST request to the web interface (guestaccess.aspx). After waiting for the log to be flushed, the script attempts to authenticate to the SFTP service as an arbitrary user, using the poisoned log file as a key source. If successful, the attacker can impersonate any user and list their files. The script is written in Python, uses the paramiko library for SSH/SFTP, and requires attacker-supplied SSH key files. The repository structure is minimal, with only a README and the exploit script. The exploit is operational and demonstrates a real authentication bypass, not just detection.
This repository contains a working proof-of-concept exploit for CVE-2024-5806, a critical authentication bypass vulnerability in Progress MOVEit Transfer (fixed in version 2024.0.2). The exploit is implemented in a single Python script ('watchTowr-vs-progress-moveit_cve-2024-5806.py') and requires the attacker to provide both PEM and PPK formatted private keys. The attack works by repeatedly sending crafted POST requests to the MOVEit Transfer web interface to poison a log file ('C:\MOVEitTransfer\Logs\DMZ_WEB.log') with attacker-controlled SSH public key data. After waiting for the logs to flush, the script attempts to authenticate to the SFTP service as an arbitrary user, leveraging the poisoned log file to bypass authentication. Upon success, the attacker can list and access files in the victim user's home directory. The repository also includes a README with usage instructions and a requirements.txt listing Python dependencies (paramiko, requests, urllib3). The exploit targets Windows-based MOVEit Transfer servers and requires network access to both the web and SFTP services.
