⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access and extraction of sensitive information including user credentials, personal data, and booking records.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection execution.
🎯 Exploit Status
Multiple public exploit scripts are available. Exploitation requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds and code fixes manually.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the city parameter
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM services WHERE city = ?'); $stmt->bind_param('s', $city);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:city "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from sensitive data
- Deploy intrusion detection systems to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test the /service-list endpoint with SQL injection payloads like: /service-list?city=' OR '1'='1Check Version:
Check application files for version information, typically in config files or footerVerify Fix Applied:
Test with the same payloads after implementing fixes - should return error or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests with SQL keywords in city parameter
- Requests to /service-list with suspicious parameters
Network Indicators:
- HTTP requests containing SQL injection patterns in query strings
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri_path="/service-list" AND (query_string="*OR*" OR query_string="*UNION*" OR query_string="*SELECT*" OR query_string="*--*" OR query_string="*'*")
