💻 Affected Systems
- SourceCodester/Campcodes School Log Management System
📦 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.
Likely Case
Unauthorized access to sensitive student/administrator data, system manipulation, and potential lateral movement within the network.
If Mitigated
Limited impact with proper input validation and WAF rules blocking SQL injection patterns.
🎯 Exploit Status
Public exploit code is available, making this easily weaponizable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the Username parameter in ajax.php
Modify /admin/ajax.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $username);
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the login endpoint
Add WAF rule: Deny requests to /admin/ajax.php?action=login containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls and monitor all traffic to /admin/ajax.php
- Implement network segmentation to limit database access from the web application server
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /admin/ajax.php?action=login&Username=admin' OR '1'='1Check Version:
Check the software version in the system interface or configuration filesVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL patterns
- Requests to /admin/ajax.php with suspicious parameters
Network Indicators:
- HTTP requests containing SQL keywords targeting the vulnerable endpoint
- Unusual database query patterns from the application server
SIEM Query:
source="web_logs" AND uri="/admin/ajax.php" AND (query="*OR*1=1*" OR query="*UNION*SELECT*" OR query="*'--*" OR query="*;--*")🔗 References
