CVE-2025-6160
📋 TL;DR
This critical SQL injection vulnerability in SourceCodester Client Database Management System 1.0 allows attackers to execute arbitrary SQL commands via the user_id parameter in /user_customer_create_order.php. Attackers can potentially read, modify, or delete database contents, and in some cases achieve remote code execution. All deployments of version 1.0 are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access and modification, potentially including sensitive customer information and system credentials.
If Mitigated
Limited impact if proper input validation and WAF rules are in place, though risk remains if SQL injection filters are bypassed.
🎯 Exploit Status
Exploit details are publicly available on GitHub. The SQL injection appears to require some level of authentication based on the vulnerable endpoint name, but this hasn't been fully confirmed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch is available. Consider the following: 1. Check SourceCodester website for updates. 2. If no patch exists, implement workarounds or consider replacing the software. 3. Apply input validation and parameterized queries manually if source code is accessible.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the user_id parameter in /user_customer_create_order.php
Input Validation Filter
allImplement server-side validation to restrict user_id parameter to expected formats (e.g., numeric only)
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation and rate limiting
- Implement network segmentation to restrict database access from the application server only
🔍 How to Verify
Check if Vulnerable:
Test the /user_customer_create_order.php endpoint with SQL injection payloads in the user_id parameter (e.g., user_id=1' OR '1'='1). Monitor for database errors or unexpected responses.Check Version:
Check application version in admin panel or review source code files for version indicatorsVerify Fix Applied:
After applying fixes, retest with SQL injection payloads. Verify that inputs are properly sanitized and no database errors are returned. Check that parameterized queries are implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts followed by SQL injection patterns
- Requests to /user_customer_create_order.php with suspicious user_id parameters
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, INSERT, etc.) in parameters
- Abnormal database query patterns from application server
SIEM Query:
source="web_logs" AND uri="/user_customer_create_order.php" AND (param="*user_id=*'*" OR param="*user_id=*%27*" OR param="*user_id=* UNION *" OR param="*user_id=* SELECT *")
