Hey Hunter's,
DarkShadow here back again, just dropping a critical RCE...
🔥Jenkins Git Parameter Plugin – Command Injection💀
The Jenkins plugin “Git Parameter” (versions up to 439.vb_0e46ca_14534) allows attackers to inject arbitrary Git parameter values into shell commands.
Approximately 15,000 publicly accessible Jenkins servers have authentication disabled! And some others allow anyone to create accounts freely.
POC payload:
insert here $(YOUR OS COMMANDS)
So guy's if you like to more read latest POC's show your love's and share.

if you ever got a LFI vector parameter, then not just try LFI payloads.
Parameter: &Path= ❎LFI ✅RCE

RCE in tcp connection (rocketMQ protocol)
You guys are always hunt vulnerabilities in HTTP/HTTPS connections right?
Try different:
1. Find your target in scope all ip address
2. Enumerate all service
3. Grep all ip address which are using any tcp connection service's.
4. Note all ip, ports and service versions.
5. Start to read the service official documentation that how it's works.
6. Use tool ncat, socat or python script for sending request to testing.
Now come back to the POC:
1. Make a .bin file where save the payload.
2. Use ncat to send the request.
3. In burp collaborator the user-agent is curl means clear blind RCE.

I Hope this method also help you to improve your bug hunting. Now guys show your love ❤️

DarkShadow here back again, dropping a RCE in mail input field!
Listen, this is very important.
1. When a sign-in/sign-up page comes, use a normal email using your burp collaborator.
2. If you got any HTTP hit back in your burp, then don't stop thinking by SSRF.
3. Now test command injection payload on the mail input field.
4. Don't use URL encoding in space like %20 always use ${IFS} to replace spaces.
5. It's essential when you try here RCE also try blind OS injection payloads.
I Hope this method also help you to improve your bug hunting. Now guys show your love ❤️

Hey Hunter's,
DarkShadow is here back again, and dropping again a RCE method!
💀Steps to reproduce:☠️
1. Collect all possible js endpoints.
You can use my DarkEndFinder for quick js find.
2. Grep .map files from js files.
3. Use jsmap-inspector to debug clearly
4. Read manually one by one js logics and note down all the critical endpoints
5. Now play in your burp also use curl
AND I HOPE YOU KNOW WHAT SHOULD YOU DO NEXT... ALSO READ THE IMAGES.
Tip:
To collect more js use wayback machine urls.
So guy's if you really enjoyed to read methods then show your love❤️

💀Blind Remote Code Execution in Cookies☠
NOTE:
–in some servers use sh as default not bash, so in your payload sh payloads are perfect.
–don't forget to check the cookies while you tested any webapp, because in some cases Cookies are intersect with bash process.
–Last but seriously important, Always use burp collab for blind testing...

- if you find any endpoint which works to validate any code its a gold mine, try RCE payloads.

🚨 Import schema from H2 Database → RCE via EXEC Alias ⚡
Creating an alias to execute system commands via Java Runtime
🔍 Quick Analysis:
- Default oken validation
- H2 database exposed with unsafe configurations
- Ability to create custom ALIAS → leads to RCE
- No proper input validation or restriction on JDBC params
🧠 Bug Bounty Tips:
- Always check hidden/internal endpoints like "/getSchema", "/actuator", "/env"
- Look for H2 / embedded DB usage → often misconfigured
- Try injecting JDBC params (INIT, TRACE, etc.)
- Don’t ignore default tokens or exposed headers
- Think beyond SQLi → DB features themselves can be weaponized

⚡️Blind RCE via Chaining Requests💀
one word for all:
"To exploit any high severity vulnerability you have to analyze and chain multiple request components"
How to approach chaining a bug:
• First open your target in burpsuite (disable browser extensions to reduce other requests)
• Brows the target maually as much possible (don't run automatic crawler do first manually)
• Turn off proxy and review porxy history and send all the imporetent requests in 'Organizer' tab
• Now play in repeater, and if you got anything interesting see the serial number of the request in proxy history
• For chaining with other request analyze after the request history (this will help you to understand whats your second step request now)
THIS IS HOW YOU CAN FIND CRITICAL BUGS BY CHAINING THEM
