CVE-2025-4718
📋 TL;DR
This critical SQL injection vulnerability in Campcodes Sales and Inventory System 1.0 allows attackers to execute arbitrary SQL commands via the 'last' parameter in the customer_add.php file. Remote attackers can potentially access, modify, or delete database contents. All users running the affected software version are at risk.
💻 Affected Systems
- Campcodes Sales and Inventory System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access and extraction of sensitive customer information, inventory data, and potentially administrative credentials.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub, making this easily weaponizable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for all user inputs in the application.
Modify PHP code to use prepared statements: $stmt = $conn->prepare('INSERT INTO customers (last) VALUES (?)'); $stmt->bind_param('s', $last);
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests.
Configure WAF rules to block SQL injection patterns in POST/GET parameters
🧯 If You Can't Patch
- Isolate the system from the internet using firewall rules to restrict access to trusted IPs only.
- Implement database-level controls: Use least privilege accounts, enable logging, and regularly audit database access.
🔍 How to Verify
Check if Vulnerable:
Test the /pages/customer_add.php endpoint with SQL injection payloads in the 'last' parameter and observe database errors or unexpected behavior.Check Version:
Check the software version in the application interface or configuration files; look for version 1.0 indicators.Verify Fix Applied:
After implementing fixes, retest with SQL injection payloads to confirm they are properly blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts or parameter manipulation in access logs
- Unexpected database queries from web application user
Network Indicators:
- HTTP requests to /pages/customer_add.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND (url="/pages/customer_add.php" AND (param="last" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT"))
