💻 Affected Systems
- CodeAstro Student Grading System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, modification, deletion, or potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access, privilege escalation, and data manipulation affecting student records and system functionality.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit details are publicly available, making this easily weaponizable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://codeastro.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allImplement proper input validation and use parameterized queries/prepared statements for the studentId parameter.
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block exploitation attempts.
🧯 If You Can't Patch
- Isolate the system from internet access and restrict internal network access
- Implement strict database permissions and monitor for unusual SQL queries
🔍 How to Verify
Check if Vulnerable:
Test the studentsubject.php endpoint with SQL injection payloads in the studentId parameter. Check application version in admin panel or source files.Check Version:
Check admin panel or look for version information in application files/configurations.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and that parameterized queries are implemented in studentsubject.php.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts or parameter manipulation in web server logs
Network Indicators:
- HTTP requests to studentsubject.php with SQL injection patterns in parameters
SIEM Query:
source="web_server" AND uri="*studentsubject.php*" AND (param="*studentId=*'*" OR param="*studentId=*;*" OR param="*studentId=*--*")
