Mastering the Art of Bypassing 403 Forbidden Errors

Are you a security enthusiast or bug bounty hunter looking for an efficient way to bypass those pesky 403 Forbidden errors? Meet our newly updated 403 Bypass Script—a simple yet effective tool for exploring potential bypassing techniques. With its advanced features, you can automate testing for subdomains, single domains, and specific paths to uncover hidden vulnerabilities.

Why Bypass 403 Errors?

The 403 Forbidden error often blocks access to restricted resources. However, sometimes misconfigurations allow attackers to bypass these restrictions using creative techniques. As a penetration tester or ethical hacker, testing such bypass methods is crucial to identifying and fixing potential security flaws.

Our script is designed to automate this process with various techniques, saving you time and effort while providing reliable results.

Key Features

1. Supports Multiple Use Cases

The script can handle various scenarios, whether you are testing a single domain or an entire list of subdomains. Additionally, you can append custom wordlists or specify single paths for testing.

2. Customizable Output

By default, the script saves all successful 200 OK responses to 200-outputs.txt. You can also specify a custom output file, ensuring flexibility in managing results.

3. Persistent Output File

The script ensures that previously saved results are never overwritten. Instead, new results are appended, allowing you to maintain a complete history of your findings.

4. Advanced Bypass Techniques

The script employs a variety of bypassing methods, including:

Header-based techniques (e.g., X-Forwarded-For, X-Originating-IP)
Payload-based techniques (e.g., ..%2f, /./, /*, %20)

5. Real-Time Feedback

Responses from the server are displayed in real-time, with 200 status responses highlighted in green for better visibility.

How It Works

The script tests different bypassing techniques by sending crafted requests to the target domain or subdomains. It checks for responses with the HTTP 200 OK status code, indicating successful access.

Example Techniques Used:

Headers: Adding X-Forwarded-For headers with spoofed values.
Payloads: Using path traversal sequences like /..;/ or %2e%2e.

Installation

Getting started is easy. Clone the repository, make the script executable, and you’re ready to go.

The script supports multiple use cases, making it versatile for various testing scenarios. Below are examples of how to use it:

1. Single Domain Without Wordlist

Check for bypassing techniques on the root path of a single domain.
./bypass-403.sh https://example.com

2. Single Domain With Custom Output File

Save successful responses to a custom output file.
./bypass-403.sh https://example.com -o results.txt

3. Subdomain List Without Wordlist

Test multiple subdomains from a file.
./bypass-403.sh subdomains.txt

4. Subdomain List With Wordlist

Append each word from the wordlist to subdomains and test.
./bypass-403.sh subdomains.txt -w wordlist.txt

5. Subdomain List With Wordlist and Custom Output

Save results to a custom output file.
./bypass-403.sh subdomains.txt -w wordlist.txt -o custom-results.txt

Wordlist Format

The wordlist should include paths without a preceding /. For example:
admin
secret
login
dashboard
