CVE-2024-50828
📋 TL;DR
A SQL injection vulnerability in the kashipara E-learning Management System allows attackers to manipulate database queries through the 'd' parameter in the /admin/edit_department.php endpoint. This affects all users running version 1.0 of the software, potentially compromising the entire database.
💻 Affected Systems
- kashipara E-learning Management System Project
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized access to sensitive student/teacher data, grade manipulation, and potential privilege escalation within the system.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting attackers to error-based information disclosure.
🎯 Exploit Status
Exploitation requires admin access to reach the vulnerable endpoint, but SQL injection techniques are well-documented and easy to execute.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
1. Review the vulnerable file /admin/edit_department.php
2. Replace raw SQL queries with parameterized prepared statements
3. Implement proper input validation for the 'd' parameter
4. Test the fix thoroughly before deployment
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests to the vulnerable endpoint.
Access Restriction
linuxRestrict access to /admin/edit_department.php to specific trusted IP addresses only.
# Apache:
<Location "/admin/edit_department.php">
Require ip 192.168.1.0/24
</Location>
# Nginx:
location /admin/edit_department.php {
allow 192.168.1.0/24;
deny all;
}
🧯 If You Can't Patch
- Implement network segmentation to isolate the e-learning system from critical infrastructure.
- Enable detailed logging and monitoring for all access to the /admin/edit_department.php endpoint.
🔍 How to Verify
Check if Vulnerable:
Test the /admin/edit_department.php endpoint with SQL injection payloads in the 'd' parameter (e.g., d=1' OR '1'='1). Monitor for database errors or unexpected behavior.Check Version:
Check the software version in the system configuration or about page, or examine the source code for version identifiers.Verify Fix Applied:
Attempt the same SQL injection tests after applying fixes. Verify that parameterized queries are used and input validation rejects malicious payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in request parameters
- Multiple failed login attempts followed by access to /admin/edit_department.php
- Database error messages in application logs
Network Indicators:
- HTTP requests to /admin/edit_department.php with SQL keywords in parameters
- Unusual database query patterns from the application server
SIEM Query:
source="web_logs" AND uri="/admin/edit_department.php" AND (param="d" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|exec|--|#|;)")
