CVE-2024-22196
📋 TL;DR
CVE-2024-22196 is a SQL injection vulnerability in Nginx-UI where user-controlled 'order' and 'sort_by' query parameters are appended to SQL queries without sanitization. This allows attackers to execute arbitrary SQL commands, potentially leading to data theft or manipulation. All users running Nginx-UI versions before 2.0.0.beta.9 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise allowing data theft, modification, or deletion, and potential server takeover via SQL injection to execute system commands.
Likely Case
Unauthorized access to sensitive monitoring data including server metrics, configuration details, and potentially authentication information.
If Mitigated
Limited information disclosure if database permissions are properly restricted and input validation is implemented elsewhere.
🎯 Exploit Status
SQL injection vulnerabilities are commonly weaponized and this appears to be a straightforward injection point requiring minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.0.beta.9
Vendor Advisory: https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-h374-mm57-879c
Restart Required: Yes
Instructions:
1. Backup your current configuration. 2. Stop the Nginx-UI service. 3. Update to version 2.0.0.beta.9 or later using your package manager or by downloading from GitHub. 4. Restart the Nginx-UI service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Proxy
allDeploy a reverse proxy or WAF that validates and sanitizes query parameters before they reach Nginx-UI.
# Configure nginx as reverse proxy with parameter validation
location /nginx-ui/ {
proxy_pass http://localhost:8080;
# Add parameter validation rules here
}
Network Access Restriction
allRestrict access to Nginx-UI interface to trusted IP addresses only.
# In nginx configuration:
location /nginx-ui/ {
allow 192.168.1.0/24;
allow 10.0.0.0/8;
deny all;
proxy_pass http://localhost:8080;
}
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Nginx-UI from sensitive systems and limit access to authorized users only.
- Deploy a web application firewall (WAF) with SQL injection detection rules to block exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check if your Nginx-UI version is below 2.0.0.beta.9. The vulnerability exists if query parameters are not properly sanitized before SQL query construction.Check Version:
Check the Nginx-UI interface or run: grep -i version /path/to/nginx-ui/config/files or check package manager: dpkg -l | grep nginx-ui or rpm -qa | grep nginx-uiVerify Fix Applied:
After updating, test that SQL injection attempts via 'order' and 'sort_by' parameters are properly rejected or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL query patterns in application logs
- Multiple failed login attempts followed by parameter manipulation
- Requests with SQL keywords in query parameters (ORDER BY, UNION, SELECT)
Network Indicators:
- HTTP requests containing SQL injection payloads in 'order' or 'sort_by' parameters
- Unusual database query patterns from the Nginx-UI application
SIEM Query:
source="nginx-ui" AND (http_query="*ORDER BY*" OR http_query="*UNION*" OR http_query="*SELECT*" OR http_query="*FROM*" OR http_query="*WHERE*")🔗 References
