📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation, or system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive sales and inventory data, including customer information, financial records, and product details.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing in affected tables.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable by attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify /pages/product_update.php to validate and sanitize the ID parameter using prepared statements.
Replace raw SQL queries with parameterized queries using PDO or mysqli prepared statements.
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the /pages/product_update.php endpoint.
Configure WAF to block requests containing SQL keywords (SELECT, UNION, etc.) in the ID parameter.
🧯 If You Can't Patch
- Restrict network access to the system using firewall rules to allow only trusted IP addresses.
- Implement database-level controls: use least-privilege database accounts and enable SQL logging for anomaly detection.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted request to /pages/product_update.php with SQL injection payload in the ID parameter (e.g., ID=1' OR '1'='1).Check Version:
Check the system's version in the admin panel or configuration files; look for 'Campcodes Sales and Inventory System 1.0'.Verify Fix Applied:
Verify that the same SQL injection payload no longer executes and returns an error or sanitized response.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs, multiple failed login attempts, or unexpected database queries from /pages/product_update.php.
Network Indicators:
- HTTP requests to /pages/product_update.php containing SQL keywords (e.g., UNION, SELECT, --) in parameters.
SIEM Query:
source="web_logs" AND uri="/pages/product_update.php" AND (param="ID" AND value MATCHES "(?i)(union|select|--|')")
