CVE-2023-3000

9.8 CRITICAL

📋 TL;DR

This SQL injection vulnerability in Erikoglu Technology ErMon allows attackers to execute arbitrary SQL commands, potentially leading to command line execution and authentication bypass. It affects all ErMon installations before version 230602. Attackers can exploit this to gain unauthorized access and control over affected systems.

💻 Affected Systems

Products:
  • Erikoglu Technology ErMon
Versions: All versions before 230602
Operating Systems: All supported OS
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations are vulnerable. No special configuration required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with remote code execution, data exfiltration, and complete authentication bypass allowing attacker to take over the system.

🟠

Likely Case

Authentication bypass leading to unauthorized access, data manipulation, and potential command execution on the underlying system.

🟢

If Mitigated

Limited impact with proper input validation and database permissions, potentially only allowing data viewing but not modification.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SQL injection vulnerabilities are typically easy to exploit with automated tools. The authentication bypass aspect suggests minimal prerequisites for attack.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 230602

Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-23-0315

Restart Required: Yes

Instructions:

1. Download ErMon version 230602 or later from official vendor sources. 2. Backup current configuration and data. 3. Stop ErMon service. 4. Install the updated version. 5. Restart ErMon service. 6. Verify functionality.

🔧 Temporary Workarounds

Web Application Firewall

all

Deploy WAF with SQL injection protection rules to block exploitation attempts

Network Segmentation

all

Restrict access to ErMon to only trusted networks and IP addresses

🧯 If You Can't Patch

  • Implement strict input validation and parameterized queries at application level
  • Apply principle of least privilege to database accounts used by ErMon

🔍 How to Verify

Check if Vulnerable:

Check ErMon version in administration interface or configuration files. If version is earlier than 230602, system is vulnerable.

Check Version:

Check ErMon web interface or configuration files for version information

Verify Fix Applied:

Confirm ErMon version is 230602 or later and test SQL injection attempts are properly blocked.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL query patterns
  • Failed authentication attempts followed by successful access
  • Unexpected command execution in system logs

Network Indicators:

  • SQL injection payloads in HTTP requests to ErMon endpoints
  • Unusual outbound connections from ErMon server

SIEM Query:

source="ermon.log" AND ("sql" OR "injection" OR "union select" OR "' OR '1'='1")
