CVE-2025-11431
📋 TL;DR
This SQL injection vulnerability in code-projects Web-Based Inventory and POS System 1.0 allows attackers to manipulate database queries through the shopid parameter in /transaction.php. Attackers can potentially read, modify, or delete database contents. All deployments of version 1.0 are affected.
💻 Affected Systems
- code-projects Web-Based Inventory and POS System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including theft of sensitive data (customer information, financial records), data destruction, or full system takeover via subsequent attacks.
Likely Case
Data exfiltration of inventory, customer, and transaction data leading to business disruption and potential regulatory violations.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or minor data exposure.
🎯 Exploit Status
Exploit details are publicly available on GitHub. Attack requires access to the transaction functionality but no authentication beyond that.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allImplement proper input validation and use parameterized queries/prepared statements for all database operations in transaction.php
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests to /transaction.php
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test the /transaction.php endpoint with SQL injection payloads in the shopid parameter and observe database errors or unexpected behaviorCheck Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Test with SQL injection payloads after implementing fixes - should return proper error messages or reject malicious input📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server
- SQL syntax errors in application logs
- Multiple failed transaction attempts with malformed shopid values
Network Indicators:
- HTTP requests to /transaction.php with SQL keywords in parameters
- Unusual database traffic patterns from web server
SIEM Query:
source="web_logs" AND uri="/transaction.php" AND (param="shopid" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR 1=1")
