📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive student data exfiltration, administrative account takeover, and potential server-side code execution leading to full system control.
Likely Case
Unauthorized access to student records, grade manipulation, and extraction of personally identifiable information from the database.
If Mitigated
Limited data exposure if database permissions are properly restricted, but SQL injection still allows unauthorized query execution.
🎯 Exploit Status
Exploit requires access to admin interface but SQL injection is straightforward once authenticated
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify index.php to validate and sanitize ID parameter using prepared statements
Edit /admin/modules/course/index.php to replace direct SQL with parameterized queries
Web Application Firewall Rules
allImplement WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /admin/modules/course/index.php with suspicious SQL patterns in ID parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test the ID parameter in /admin/modules/course/index.php with SQL injection payloads like ' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts followed by SQL injection patterns
- Unusual database queries from web application user
Network Indicators:
- HTTP requests to /admin/modules/course/index.php with SQL keywords in parameters
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/admin/modules/course/index.php" AND (param="ID" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR '1'='1")
