CVE-2024-6699 Overview
CVE-2024-6699 is a critical SQL Injection vulnerability affecting Mikafon Electronic Inc. Mikafon MA7 firmware. This vulnerability allows attackers to manipulate SQL queries through improper neutralization of special elements, potentially enabling unauthorized access to backend databases, data exfiltration, and system compromise. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
This SQL Injection vulnerability in Mikafon MA7 firmware allows unauthenticated remote attackers to execute arbitrary SQL commands against backend databases, potentially leading to complete data compromise and unauthorized system access.
Affected Products
- Mikafon MA7 Firmware versions from v3.0 before v3.1
- Mikafon MA7 Hardware Device

Technical Details for CVE-2024-6699
Vulnerability Analysis
This SQL Injection vulnerability exists due to improper input validation in the Mikafon MA7 firmware. When user-supplied input is processed by the application, special characters used in SQL syntax are not properly neutralized before being incorporated into SQL queries. This allows an attacker to inject malicious SQL statements that are then executed by the database server.
The vulnerability is network-accessible with no authentication required, meaning any attacker with network connectivity to the affected device can attempt exploitation. Successful exploitation can result in high confidentiality and integrity impacts, allowing attackers to read, modify, or delete sensitive data stored in the database.
Root Cause
The root cause of this vulnerability is the failure to properly sanitize or parameterize user input before incorporating it into SQL queries. The affected firmware versions (v3.0 to before v3.1) do not implement adequate input validation or prepared statements, allowing SQL metacharacters to be interpreted as query commands rather than literal data.
Attack Vector
The attack vector for CVE-2024-6699 is network-based, requiring no user interaction or prior authentication. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable input fields or parameters in the Mikafon MA7 web interface.
SQL injection attacks against this vulnerability could take various forms including:
- Union-based SQL injection to extract data from other database tables
- Blind SQL injection using boolean or time-based techniques to infer database contents
- Error-based SQL injection leveraging verbose error messages to extract information
- Stacked queries to execute multiple SQL statements including data manipulation or administrative commands
For detailed technical information, refer to the USOM Security Notification TR-24-1105.
Detection Methods for CVE-2024-6699
Indicators of Compromise
- Unusual SQL error messages in web server or application logs
- Abnormal database query patterns or execution times
- Unexpected data access or modification in database audit logs
- HTTP requests containing SQL syntax characters such as single quotes, semicolons, or comment sequences in parameters
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block common SQL injection patterns
- Monitor database query logs for anomalous or malformed SQL statements
- Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
- Enable verbose logging on the Mikafon MA7 device and review for suspicious input patterns
Monitoring Recommendations
- Establish baseline network traffic patterns to and from Mikafon MA7 devices for anomaly detection
- Configure alerts for authentication failures or unusual administrative access attempts
- Implement network segmentation monitoring to detect lateral movement following potential compromise
- Review database access logs regularly for unauthorized data extraction attempts
How to Mitigate CVE-2024-6699
Immediate Actions Required
- Upgrade Mikafon MA7 firmware to version v3.1 or later immediately
- Restrict network access to Mikafon MA7 devices using firewall rules or network segmentation
- Implement a web application firewall (WAF) in front of vulnerable devices as an interim protection measure
- Review database logs for evidence of prior exploitation attempts
Patch Information
Mikafon Electronic Inc. has addressed this vulnerability in Mikafon MA7 firmware version v3.1. Organizations should obtain the latest firmware update from the vendor and apply it to all affected devices. Consult the USOM Security Notification TR-24-1105 for additional guidance.
Workarounds
- Place affected Mikafon MA7 devices behind a properly configured web application firewall with SQL injection detection rules
- Implement strict network access controls to limit connectivity to trusted IP addresses only
- Disable remote administration interfaces if not required for operations
- Monitor all traffic to and from affected devices until patching is complete
Network segmentation example for isolating vulnerable devices:
# Configuration example
# Example iptables rules to restrict access to Mikafon MA7 device
# Replace 192.168.1.100 with the actual device IP
# Replace 10.0.0.0/24 with your trusted management network
# Block all incoming traffic to the device by default
iptables -A INPUT -d 192.168.1.100 -j DROP
# Allow only trusted management network
iptables -I INPUT -s 10.0.0.0/24 -d 192.168.1.100 -j ACCEPT
# Log blocked connection attempts for monitoring
iptables -I INPUT -d 192.168.1.100 -j LOG --log-prefix "MIKAFON_BLOCKED: "
