Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
proc/self/environ
Linux process-environment pseudo-file, a classic local-file-inclusion and SSRF target
What an attacker could do
On a successful local file inclusion or path traversal, this leaks the process environment including DB passwords, API keys, and session secrets, and is a classic vector for environ-based code execution.
How to defend it
Validate and canonicalize all file paths, disable inclusion of user-controlled paths, run with allow_url_include off, and apply least-privilege file permissions to block traversal.
