📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, or deletion; potential privilege escalation to system-level access if database permissions are misconfigured.
Likely Case
Unauthorized access to sensitive student/course data, grade manipulation, or system disruption through database corruption.
If Mitigated
Limited impact with proper input validation and database permission restrictions in place.
🎯 Exploit Status
The exploit has been publicly released and requires minimal technical skill to execute. Attack vectors are straightforward SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch is available. Consider implementing input validation and parameterized queries as temporary mitigation until an official fix is released.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to reject malicious SQL characters in the csslc parameter
Modify COUNT3s5.php to validate csslc input using regex patterns or whitelist acceptable values
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Configure WAF to block requests containing SQL keywords (SELECT, UNION, etc.) in the csslc parameter
🧯 If You Can't Patch
- Isolate the vulnerable system from internet access and restrict internal network access
- Implement database-level controls: use least-privilege database accounts and enable audit logging
🔍 How to Verify
Check if Vulnerable:
Test the /Profilers/PriProfile/COUNT3s5.php endpoint with SQL injection payloads in the csslc parameter and observe database errors or unexpected behaviorCheck Version:
Check the software version in the application interface or configuration files; look for 'CourseSelectionSystem 1.0'Verify Fix Applied:
After implementing mitigations, test with the same SQL injection payloads to confirm they are blocked or properly handled📡 Detection & Monitoring
