CVE-2025-6840
📋 TL;DR
This critical SQL injection vulnerability in code-projects Product Inventory System 1.0 allows remote attackers to execute arbitrary SQL commands through the login page's username parameter. Attackers can potentially access, modify, or delete database contents. All users running the vulnerable version are affected.
💻 Affected Systems
- code-projects Product Inventory System
📦 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 functions allow it.
Likely Case
Unauthorized database access allowing data extraction, privilege escalation, and potential system takeover.
If Mitigated
Limited impact with proper input validation and database permissions, though SQL injection attempts would still be logged.
🎯 Exploit Status
Public proof-of-concept available on GitHub. SQL injection via username parameter requires no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameterized queries or input validation to the login.php file to sanitize username input.
Modify /index.php to use prepared statements with parameterized queries for SQL operations
Web Application Firewall
allDeploy WAF rules to block SQL injection patterns in login requests.
Configure WAF to block requests containing SQL keywords in username parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database server access
🔍 How to Verify
Check if Vulnerable:
Test login page with SQL injection payloads in username field (e.g., admin' OR '1'='1).Check Version:
Check software version in admin panel or readme files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and return proper error handling.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Multiple failed login attempts with SQL keywords
Network Indicators:
- HTTP POST requests to /index.php containing SQL injection patterns
SIEM Query:
source="web_logs" AND uri="/index.php" AND (username="*' OR*" OR username="*' UNION*" OR username="*' SELECT*")
