CVE-2025-4226
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul/Campcodes Cyber Cafe Management System 1.0 allows remote attackers to execute arbitrary SQL commands via the compname/comploc parameters in /add-computer.php. This can lead to database compromise, data theft, or system takeover. All users running version 1.0 without proper input validation are affected.
💻 Affected Systems
- PHPGurukul/Campcodes Cyber Cafe Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access, modification, or deletion of cyber cafe management data including customer information, billing records, and system configurations.
If Mitigated
Limited impact with proper input validation, parameterized queries, and web application firewall rules blocking SQL injection patterns.
🎯 Exploit Status
Exploit details are publicly available on GitHub and vuldb.com, making this easily weaponizable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries and input validation.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization for compname and comploc parameters before processing.
Modify /add-computer.php to use prepared statements: $stmt = $conn->prepare('INSERT INTO computers (compname, comploc) VALUES (?, ?)'); $stmt->bind_param('ss', $compname, $comploc);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting /add-computer.php endpoint.
Add WAF rule: deny requests to /add-computer.php containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Disable or restrict access to /add-computer.php endpoint using .htaccess or web server configuration
- Implement network segmentation to isolate the vulnerable system from critical assets
🔍 How to Verify
Check if Vulnerable:
Test the /add-computer.php endpoint with SQL injection payloads in compname or comploc parameters and observe database errors or unexpected behavior.Check Version:
Check software version in admin panel or review source code headers for version informationVerify Fix Applied:
After implementing fixes, test with the same SQL injection payloads to confirm they are properly rejected or sanitized without affecting legitimate functionality.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts following SQL injection patterns
- Unexpected database queries from web server IP
Network Indicators:
- HTTP requests to /add-computer.php containing SQL keywords in parameters
- Unusual database traffic patterns from web application server
SIEM Query:
source="web_logs" AND uri="/add-computer.php" AND (param="compname" OR param="comploc") AND (value="*UNION*" OR value="*SELECT*" OR value="*OR 1=1*")
