⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, and potential server takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized access to sensitive student/administrator data, grade manipulation, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://1000projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the 'batch' parameter before processing
Modify /admin_info.php to validate and sanitize all user inputs using prepared statements or parameterized queries
Web Application Firewall
allDeploy WAF rules to block SQL injection attempts
Add WAF rule: deny requests containing SQL keywords in batch parameter
🧯 If You Can't Patch
- Block external access to /admin_info.php endpoint using firewall rules
- Implement strict database user permissions with least privilege principle
🔍 How to Verify
Check if Vulnerable:
Test /admin_info.php with SQL injection payloads in batch parameter (e.g., batch=1' OR '1'='1)Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts via /admin_info.php
- SQL keywords in batch parameter requests
Network Indicators:
- Unusual database connection patterns from web server
- Large data transfers from database
SIEM Query:
source="web_logs" AND uri="/admin_info.php" AND (batch CONTAINS "UNION" OR batch CONTAINS "SELECT" OR batch CONTAINS "OR")
