Hello, fellow bug-hunters, hackers, and all you curious netizens! 👋
I’m AIwolfie, a passionate bug-hunter who loves breaking things (responsibly) and turning websites into obedient alert-box generators. With a cup of chai in one hand and a payload in the other, I spend my time hunting for vulnerabilities and sharing my adventures with the community.
Today, I bring you the story of a cute little bug that ended up as a full-blown Reflected Cross-Site Scripting (XSS) vulnerability. But wait, this isn’t just another bug bounty article — it’s got drama, payloads, and, of course, lots of alert boxes!
Grab your chai ☕, sit back, and let me tell you about this “epic” find.
The Target Website (Redacted for Security 😇)
It all started when I stumbled upon a search functionality on a website. You know the type — enter something like “pizza,” and it throws a million search results at you (because they desperately want you to click something).
I thought, “Hmm… Could this be my next jackpot? 🤔”
So, I entered the most innocent search query ever:<script>alert(1)</script>
Pop Goes the Website!
BOOM 💥! My favorite little alert box popped up, and I couldn’t help but grin like a kid who just found extra fries at the bottom of the McDonald’s bag. 🍟
The website was reflecting my input without any validation or sanitization. Here’s the magical URL (redacted, of course):
https://[REDACTED].com/search?search=<script>alert(1)</script>
What does this mean? It means the website was vulnerable to Reflected XSS — one of the most common (but super-dangerous) web vulnerabilities.
What’s the Big Deal?
Now, you might say, “Bro, it’s just an alert box. Chill.” But no, dear reader, this is a big deal.
Imagine what a bad actor could do with this:
- Steal session cookies 🍪 (a hacker’s favorite snack).
- Redirect users to malicious sites 🕵️♂️.
- Deface the website (or make it Rickroll users 🎵).
Basically, XSS can turn a website into a hacker’s playground 🎢.
Payloads FTW 🎯
Oh, but the fun didn’t stop there! I decided to test a few more payloads because, why not? 😈
Payload 1: The OG
<script>alert(1)</script>
Result? Instant popup. The website was screaming for help like a Bollywood damsel in distress.
Payload 2: Sneaky Sneaky
<img src=x onerror="alert(document.cookie)">
Result? Another popup, but this one can potentially steal cookies (if not properly secured).
Lessons for Developers 👨💻👩💻
Hey devs, I know you work hard, but let me drop some free gyaan (knowledge):
1. Sanitize Input:
Don’t trust user input. Ever. Escape those < > " ' &
characters like they’re your ex’s text messages.
2. Output Encoding:
Use proper encoding before rendering user data in HTML, JavaScript, or anywhere else.
3. CSP to the Rescue:
Implement a solid Content Security Policy (CSP) to block unauthorized scripts.
Sharma Ji’s Son Can Also Learn XSS
Bug-hunting isn’t rocket science (sorry, Sharma Ji’s son 🚀). Here’s how you can start testing for XSS:
- Look for input fields (search bars, comments, etc.).
- Test with payloads like: <script>alert(1)</script>
- If you see an alert box, congrats!
Closing Thoughts
Finding this bug was like discovering an unguarded treasure chest in an open field. 🪙 But let’s not forget the bigger picture: responsible disclosure. Always report bugs responsibly and help make the internet safer.
Until next time, keep hunting, keep learning, and remember: alerts may be basic, but bugs are priceless. 💻🐞
Stay safe. Hack smart.
