📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized data access, credential theft, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and WAF protection, though SQL injection attempts may still be logged.
🎯 Exploit Status
Exploit details are publicly available on GitHub and vuldb.com, making this easily weaponizable.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries manually, or replace with a secure alternative.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for the 'fname' parameter in /book_car.php.
Edit /book_car.php to validate and sanitize user inputs before database queries.
Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts targeting the vulnerable endpoint.
Configure WAF rules to detect and block SQL injection patterns on /book_car.php.
🧯 If You Can't Patch
- Isolate the vulnerable system from the internet and restrict access to authorized users only.
- Implement network segmentation and monitor for unusual database queries or access patterns.
🔍 How to Verify
Check if Vulnerable:
Test the /book_car.php endpoint with SQL injection payloads in the 'fname' parameter and observe database errors or unexpected behavior.Check Version:
Check the software version in the application's admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts or database errors
Network Indicators:
- HTTP requests to /book_car.php with SQL injection patterns in parameters
SIEM Query:
source="web_server" AND url="/book_car.php" AND (param="fname" AND value CONTAINS "' OR '1'='1" OR value CONTAINS "UNION SELECT" OR value CONTAINS "--")
