Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: SQL Injection in ZkTeco OEM devices.
💥 **Consequences**: Attackers can execute **arbitrary code** due to missing protection mechanisms. Critical integrity and confidentiality loss.

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: **SQL Injection** (CWE-121).
⚠️ **Flaw**: Lack of input validation/sanitization allowing malicious SQL commands to bypass security controls.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected Products**:
• ZkTeco ProFace X
• Smartec ST-FR043
• Smartec ST-FR041ME
• ZAM170-NF-1.8.25-7354-Ver1.0.0

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

🔓 **Privileges**: Remote Code Execution (RCE).
📊 **Data**: Full access to database contents.
🌐 **Scope**: High impact on Confidentiality, Integrity, and Availability (CVSS H/H/H).

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

📉 **Threshold**: **LOW**.
🔑 **Auth**: None required (PR:N).
🌍 **Access**: Network accessible (AV:N).
⚡ **Complexity**: Low (AC:L). Easy to exploit remotely.

Question 6

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

Accepted Answer

📂 **Public Exp**: Reference link provided (GitHub Advisory).
🔍 **PoC**: Specific PoC code not listed in data, but advisory exists.
⚠️ **Risk**: Wild exploitation likely given low barrier.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**: Scan for affected firmware versions (ZAM170-NF...).
🕵️ **Detection**: Look for SQL injection patterns in API endpoints.
📡 **Tools**: Use vulnerability scanners targeting ZkTeco OEM devices.

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

🛠️ **Fix**: Check vendor for firmware update.
📅 **Published**: 2024-05-21.
🔗 **Ref**: [K-ZkTeco-2023-006](https://github.com/klsecservices/Advisories/blob/master/K-ZkTeco-2023-006.md).

Question 9

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch?**:
1. **Isolate** device from public internet.
2. **Restrict** network access to trusted IPs only.
3. **Monitor** logs for SQL injection attempts.

Question 10
