dontgo403 is a tool to bypass 40X errors.

Installation

Grab the latest release for your OS from RELEASES

Or compile by your own:

git clone https://github.com/devploit/dontgo403; cd dontgo403; go get; go build

Customization

If you want to edit or add new bypasses, you can add it directly to the specific file in payloads folder and the tool will use it.

Options

./dontgo403 -h

Command line application that automates different ways to bypass 40X codes.

Usage:
  dontgo403 [flags]

Flags:
  -i, --bypassIp string       Try bypass tests with a specific IP address (or hostname). i.e.: 'X-Forwarded-For: 192.168.0.1' instead of 'X-Forwarded-For: 127.0.0.1'
  -d, --delay int             Set a delay (in ms) between each request (default 0ms)
  -f, --folder string         Define payloads folder (if it's not in the same path as binary)
  -H, --header strings        Add a custom header to the requests (can be specified multiple times)
  -h, --help                  help for dontgo403
      --http                  Set HTTP schema for request-file requests (default HTTPS)
  -t, --httpMethod string     HTTP method to use (default 'GET')
  -m, --max_goroutines int    Set the max number of goroutines working at same time (default 50)
      --nobanner              Set nobanner ON (default OFF)
  -p, --proxy string          Proxy URL. For example: http://127.0.0.1:8080

Basic usage:

./dontgo403 -u https://domain.com/admin

Verbose mode + proxy enabled:

./dontgo403 -u https://domain.com/admin -p http://127.0.0.1:8080 -v

Parse request from Burp:

./dontgo403 -r request.txt

Use custom header + specific IP address for bypasses:

./dontgo403 -u https://domain.com/admin -H "Environment: Staging" -b 8.8.8.8

Set new max of goroutines + add delay between requests:

./dontgo403 -u https://domain.com/admin -m 10 -d 200
