Q: What can hackers do? (Privileges/Data)

👑 **Privileges**: Full Admin Access without login. 💻 **Data/Action**: Remote Code Execution (RCE). Attackers can take over the entire PBX system and execute arbitrary commands.

Q: Is exploitation threshold high? (Auth/Config)

🔓 **Auth**: **Unauthenticated**. No login required. 🌐 **Config**: If the Admin Control Panel is publicly accessible, exploitation is trivial. High risk if exposed to internet.

Q: Is there a public Exp? (PoC/Wild Exploitation)

💣 **Exploit**: **Yes**, Public PoC available. 🔗 GitHub repos (rxerium, blueisbeautiful, ImBIOS) provide detection scripts and SQLi exploits. Wild exploitation confirmed.

Q: How to self-check? (Features/Scanning)

🔍 **Self-Check**: Use Sucuri Labs `ioc-check` script. 🐳 **Lab**: Spin up Docker container (ImBIOS) to test. 📡 **Scan**: Look for time-based SQLi in `userman` endpoints using Nuclei templates.

Q: Is it fixed officially? (Patch/Mitigation)

🔧 **Fix**: Official patches released by Sangoma. 📥 **Action**: Upgrade Endpoint Manager module to >= 15.0.66, >= 16.0.89, or >= 17.0.3 immediately.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: Critical SQL Injection in FreePBX `userman` endpoints. 💥 **Consequences**: Unauthenticated access to Admin Panel ➡️ Remote Code Execution (RCE). Systems compromised since Aug 2025.

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: CWE-89 (SQL Injection). ❌ **Flaw**: Insufficient user data sanitization in the `userman` AJAX endpoints. Allows attackers to inject malicious SQL commands.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected Products**: FreePBX Endpoint Manager Module. 📉 **Versions**: < 15.0.66, < 16.0.89, < 17.0.3. ⚠️ **Vendor**: Sangoma/FreePBX.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

👑 **Privileges**: Full Admin Access without login. 💻 **Data/Action**: Remote Code Execution (RCE). Attackers can take over the entire PBX system and execute arbitrary commands.

Question 5
