## Introduction

`nomore403` is an innovative tool designed to help cybersecurity professionals and enthusiasts bypass HTTP 40X errors encountered during web security assessments. Unlike other solutions, `nomore403` automates various techniques to seamlessly navigate past these access restrictions, offering a broad range of strategies from header manipulation to method tampering.

## Prerequisites

Before you install and run `nomore403`, make sure you have the following:
- Go 1.15 or higher installed on your machine.

## Installation

### From Releases

Grab the latest release for your OS from our [Releases](https://github.com/devploit/nomore403/releases) page.

### Compile from Source

If you prefer to compile the tool yourself:

```bash
git clone https://github.com/devploit/nomore403
cd nomore403
go get
go build
```

## Customization

To edit or add new bypasses, modify the payloads directly in the [payloads](https://github.com/devploit/nomore403/tree/main/payloads) folder. nomore403 will automatically incorporate these changes.

## Usage

### Basic Usage

```bash
./nomore403 -u https://domain.com/admin
```

### Verbose Mode + Proxy + Specific techniques to use

```bash
./nomore403 -u https://domain.com/admin -x http://127.0.0.1:8080 -k headers,http-versions -v
```

### Parse request from Burp

```bash
./nomore403 --request-file request.txt
```

### Use custom header + specific IP address for bypasses

```bash
./nomore403 -u https://domain.com/admin -H "Environment: Staging" -b 8.8.8.8
```

### Set new max of goroutines + add delay between requests
```bash
./nomore403 -u https://domain.com/admin -m 10 -d 200
```

## Options

```bash
./nomore403 -h
Command line application that automates different ways to bypass 40X codes.

Usage:
nomore403 [flags]

Flags:
-i, --bypass-ip string Use a specified IP address or hostname for bypassing access controls. Injects this IP in headers like 'X-Forwarded-For'.
-d, --delay int Specify a delay between requests in milliseconds. Helps manage request rate (default: 0ms).
-f, --folder string Specify the folder location for payloads if not in the same directory as the executable.
-H, --header strings Add one or more custom headers to requests. Repeatable flag for multiple headers.
-h, --help help for nomore403
--http Use HTTP instead of HTTPS for requests defined in the request file.
-t, --http-method string Specify the HTTP method for the request (e.g., GET, POST). Default is 'GET'.
-m, --max-goroutines int Limit the maximum number of concurrent goroutines to manage load (default: 50). (default 50)
--no-banner Disable the display of the startup banner (default: banner shown).
-x, --proxy string Specify a proxy server for requests (e.g., 'http://server:port').
--random-agent Enable the use of a randomly selected User-Agent.
-l, --rate-limit Halt requests upon encountering a 429 (rate limit) HTTP status code.
-r, --redirect Automatically follow redirects in responses.
--request-file string Load request configuration and flags from a specified file.
--status strings Filter output by comma-separated status codes (e.g., 200,301,403)
-k, --technique strings Specify one or more attack techniques to use (e.g., headers,path-case). (default [verbs,verbs-case,headers,endpaths,midpaths,http-versions,path-case])
--timeout int Specify a max timeout time in ms. (default 6000)
--unique Show unique output based on status code and response length
-u, --uri string Specify the target URL for the request.
-a, --user-agent string Specify a custom User-Agent string for requests (default: 'nomore403').
-v, --verbose Enable verbose output for detailed request/response logging.
