CVE-2024-45622
📋 TL;DR
This vulnerability allows attackers to bypass authentication in ASIS (Aplikasi Sistem Sekolah) by exploiting SQL injection in the username parameter of index.php. Systems running ASIS versions 3.0.0 through 3.2.0 with CodeIgniter 3 are affected, potentially exposing sensitive student and administrative data.

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing unauthorized access to all student records, grades, financial data, and administrative functions, potentially leading to data theft, manipulation, or destruction.
Likely Case
Authentication bypass enabling unauthorized access to sensitive student information and administrative functions, with potential for privilege escalation within the application.
If Mitigated
Limited impact if proper input validation, WAF rules, and network segmentation prevent exploitation attempts from reaching vulnerable systems.
🎯 Exploit Status
SQL injection in authentication endpoint allows bypass without credentials. Public GitHub repository contains proof-of-concept details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check for official patch from ASIS developers
2. If no patch, implement input validation and parameterized queries
3. Update to latest ASIS version if available
4. Consider migrating to supported application
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for username parameter
Modify index.php to use CodeIgniter's query binding: $this->db->query('SELECT * FROM users WHERE username = ?', [$username]);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns in authentication requests
Add WAF rule: Detect and block SQL keywords in username parameter (e.g., UNION, SELECT, INSERT, DELETE, DROP, --, #, ' OR '1'='1)
🧯 If You Can't Patch
- Implement network segmentation to restrict access to ASIS application
- Deploy intrusion detection/prevention systems to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test authentication endpoint with SQL injection payloads in username parameter (e.g., admin' OR '1'='1) and observe if authentication bypass occurs.Check Version:
Check ASIS version in application configuration files or admin panel. For CodeIgniter: check application/config/config.php and system/core/CodeIgniter.php version constants.Verify Fix Applied:
Attempt same SQL injection payloads after implementing fixes; authentication should fail and proper error handling should occur without database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts with SQL keywords in username field
- Multiple failed login attempts followed by successful login from same IP
- Database error logs showing SQL syntax errors from authentication queries
Network Indicators:
- HTTP POST requests to index.php with SQL injection patterns in parameters
- Unusual traffic patterns to authentication endpoints
SIEM Query:
source="web_logs" AND (uri="/index.php" OR uri LIKE "%/index.php%") AND (request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%" OR request_body LIKE "%' OR '%'='%" OR request_body LIKE "%--%" OR request_body LIKE "%#%")
