CVE-2025-0210
📋 TL;DR
This critical SQL injection vulnerability in Campcodes School Faculty Scheduling System 1.0 allows attackers to execute arbitrary SQL commands via the username parameter in the /admin/ajax.php login endpoint. Remote attackers can potentially access, modify, or delete database content, including sensitive faculty and scheduling information. All deployments of version 1.0 with the vulnerable endpoint exposed are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database permissions allow.
Likely Case
Unauthorized access to sensitive faculty and scheduling data, potential privilege escalation to admin accounts, and data manipulation.
If Mitigated
Limited impact with proper input validation and database permission restrictions, though SQL injection attempts would still be logged.
🎯 Exploit Status
Public proof-of-concept available on GitHub demonstrates blind SQL injection. Exploitation requires no authentication.
🛠️ Fix & Mitigation

Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
PHPImplement parameterized queries or prepared statements for all database operations, especially in /admin/ajax.php
Modify PHP code to use PDO or mysqli prepared statements
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /admin/ajax.php?action=login containing SQL keywords in username parameter
🧯 If You Can't Patch
- Block external access to /admin/ajax.php endpoint at network firewall level
- Implement strict input validation and output encoding in application layer
🔍 How to Verify
Check if Vulnerable:
Test the /admin/ajax.php?action=login endpoint with SQL injection payloads in username parameter (e.g., admin' OR '1'='1)Check Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple failed login attempts with SQL syntax in username parameter
- Requests to /admin/ajax.php with suspicious parameters
Network Indicators:
- HTTP POST/GET requests to /admin/ajax.php containing SQL keywords (UNION, SELECT, INSERT, etc.)
SIEM Query:
source="web_server" AND (url="/admin/ajax.php" AND (username="*'*" OR username="*--*" OR username="*UNION*"))
