📋 TL;DR
This critical SQL injection vulnerability in Campcodes Complete Web-Based School Management System 1.0 allows attackers to manipulate database queries through the 'grade' parameter in /view/timetable_update_form.php. Attackers can potentially read, modify, or delete sensitive school data including student records, grades, and personal information. All users running the vulnerable version are affected.
💻 Affected Systems
- Campcodes Complete Web-Based School Management System
📦 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 execute arbitrary commands.
Likely Case
Unauthorized access to sensitive student and staff data, grade manipulation, or extraction of database credentials.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
Exploit details are publicly available in GitHub repositories. Attack requires access to the vulnerable endpoint, which may require authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Implement parameterized queries and input validation in /view/timetable_update_form.php. Consider migrating to a supported, maintained school management system.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests to the vulnerable endpoint.
Input Validation Filter
allAdd server-side validation to sanitize the 'grade' parameter before processing.
// PHP example: filter_var($_POST['grade'], FILTER_SANITIZE_STRING);
🧯 If You Can't Patch
- Block external access to the system using network firewalls or restrict to trusted IPs only.
- Disable or remove the /view/timetable_update_form.php file if functionality is not critical.
🔍 How to Verify
Check if Vulnerable:
Test the /view/timetable_update_form.php endpoint with SQL injection payloads in the 'grade' parameter and monitor for database errors or unexpected responses.
Check Version:
Check application documentation or configuration files for version information, typically in README or config.php.
Verify Fix Applied:
Verify that parameterized queries are implemented and test with SQL injection payloads to confirm they are blocked or sanitized.
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to /view/timetable_update_form.php with suspicious parameters
- Database query anomalies
Network Indicators:
- HTTP POST requests to /view/timetable_update_form.php containing SQL keywords (UNION, SELECT, etc.) in parameters
SIEM Query:
source="web_logs" AND uri_path="/view/timetable_update_form.php" AND (param="grade" AND value MATCHES "(?i).*UNION.*SELECT.*|.*OR.*1=1.*")
