📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or remote code execution on the database server
Likely Case
Unauthorized access to sensitive student/teacher data, grade manipulation, or system disruption
If Mitigated
Limited impact with proper input validation and database permissions in place

Simple parameter manipulation required, no authentication needed
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Replace vulnerable code with parameterized queries or input validation.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to ensure 'id' parameter contains only numeric values
Modify School/sub_delete.php to validate $_GET['id'] with is_numeric() or filter_var()
Web Application Firewall Rule
allBlock SQL injection patterns at the 'id' parameter
Add WAF rule to detect SQL patterns in GET parameters
🧯 If You Can't Patch
- Implement network segmentation to isolate the application from sensitive databases
- Add strict database user permissions with least privilege access
🔍 How to Verify
Check if Vulnerable:
Test School/sub_delete.php?id=5' OR '1'='1 and observe database error or unexpected behaviorCheck Version:
Check application files for version information or readme filesVerify Fix Applied:
Test with SQL injection payloads and verify they are rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web application
- SQL syntax errors in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests with SQL keywords in GET parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND (uri="*sub_delete.php*" AND (param="*id=*'*" OR param="*id=*%27*" OR param="*id=*OR*"))
