💻 Affected Systems
- Campcodes Computer Sales and Inventory System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including theft of sensitive data, administrative account takeover, and potential system destruction via SQL commands.
Likely Case
Data exfiltration of sales, inventory, and customer information, with possible authentication bypass to gain administrative privileges.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-sensitive data.
🎯 Exploit Status
Exploit details are publicly available on GitHub repositories, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries as workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization of all user inputs, particularly cash and firstname parameters.
Modify /pages/pos_transac.php to add input validation using PHP filter functions or regex patterns
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint.
Add WAF rule: Block requests to /pages/pos_transac.php?action=add containing SQL keywords in parameters
🧯 If You Can't Patch
- Isolate the system from internet access and restrict internal network access to authorized users only.
- Implement database-level controls: Use least privilege database accounts, enable SQL query logging, and regularly audit database activity.
🔍 How to Verify
Check if Vulnerable:
Test the /pages/pos_transac.php?action=add endpoint with SQL injection payloads in cash or firstname parameters and observe database errors or unexpected behavior.Check Version:
Check system documentation or configuration files for version information; typically found in about pages or system settings.Verify Fix Applied:
After implementing workarounds, test with the same SQL injection payloads to confirm they are properly blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts or parameter manipulation in web server logs
- Requests to /pages/pos_transac.php with SQL keywords in parameters
Network Indicators:
- Unusual outbound database connections from the web server
- Traffic patterns indicating data exfiltration
SIEM Query:
source="web_server" AND uri="/pages/pos_transac.php" AND (param="cash" OR param="firstname") AND (content CONTAINS "UNION" OR content CONTAINS "SELECT" OR content CONTAINS "INSERT" OR content CONTAINS "DELETE")🔗 References
