📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution on the database server.
Likely Case
Unauthorized access to sensitive student and academic records, potential authentication bypass, and data exfiltration.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation in place.
🎯 Exploit Status
SQL injection on authentication forms is easily weaponized with automated tools like sqlmap.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Contact EGPP for updated version or patch
2. If unavailable, implement workarounds immediately
3. Consider migrating to alternative software
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious payloads
Input Validation Filter
allImplement server-side input validation to reject SQL special characters in username field
🧯 If You Can't Patch
- Isolate the GESAC system from internet access using network segmentation
- Implement strict access controls and monitor all authentication attempts
🔍 How to Verify
Check if Vulnerable:
Test username parameter with SQL injection payloads like ' OR '1'='1
Check Version:
Check application version in admin panel or configuration files
Verify Fix Applied:
Attempt SQL injection tests and verify they are rejected or properly escaped
📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL syntax in username field
- Unusual database queries from web application user
Network Indicators:
- HTTP POST requests to login endpoint containing SQL keywords
- Unusual database traffic patterns
SIEM Query:
source="web_logs" AND (username="*' OR*" OR username="*;--*" OR username="*UNION*" OR username="*SELECT*" OR username="*INSERT*" OR username="*UPDATE*" OR username="*DELETE*")
