CVE-2026-0585: Online Product Reservation System SQLi Flaw

CVE-2026-0585 Overview

A SQL injection vulnerability has been identified in code-projects Online Product Reservation System version 1.0. The vulnerability exists in the /order_view.php file within the GET Parameter Handler component. Manipulation of the transaction_id parameter allows attackers to inject malicious SQL commands. This vulnerability can be exploited remotely over the network without authentication, potentially allowing unauthorized access to database contents, data modification, or data exfiltration.

Critical Impact

This SQL injection vulnerability enables remote attackers to manipulate database queries through the transaction_id parameter, potentially compromising data confidentiality, integrity, and availability of the Online Product Reservation System.

Affected Products

• code-projects Online Product Reservation System 1.0
• /order_view.php component (GET Parameter Handler)

Technical Details for CVE-2026-0585

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the order_view.php file. The application fails to properly sanitize user-supplied input passed through the transaction_id GET parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the privileges of the application's database user.

The vulnerability is classified as network-accessible with low attack complexity, requiring no privileges or user interaction to exploit. The exploit has been publicly disclosed and documented, increasing the risk of exploitation in the wild.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries or prepared statements when handling the transaction_id GET parameter in the /order_view.php file. User-controlled input is directly concatenated into SQL query strings without proper sanitization or escaping, allowing attackers to break out of the intended query structure and inject malicious SQL commands.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can craft a malicious HTTP GET request to the vulnerable /order_view.php endpoint with a specially crafted transaction_id parameter containing SQL injection payloads. Since no authentication is required, any network-accessible attacker can attempt exploitation.

The vulnerability allows attackers to:

• Extract sensitive data from the database through UNION-based or error-based injection techniques
• Modify or delete database records
• Potentially execute administrative database operations
• Bypass authentication mechanisms if user credentials are stored in the database

For detailed technical information and proof-of-concept examples, refer to the GitHub CVE Documentation and VulDB entry #339477.

Detection Methods for CVE-2026-0585

Indicators of Compromise

• Unusual or malformed GET requests to /order_view.php containing SQL syntax characters (single quotes, double dashes, semicolons, UNION keywords)
• Database error messages appearing in web server logs or application responses
• Unexpected database query patterns or execution times
• Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the transaction_id parameter
• Monitor web server access logs for requests to /order_view.php containing suspicious characters or SQL keywords
• Enable database query logging and monitor for anomalous query structures or unauthorized data access
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Configure alerts for HTTP requests containing common SQL injection payloads targeting the affected endpoint
• Monitor database server logs for failed authentication attempts or privilege escalation activities
• Implement real-time security monitoring for the web application with focus on input validation failures
• Review access logs regularly for patterns indicating automated scanning or exploitation attempts

How to Mitigate CVE-2026-0585

Immediate Actions Required

• Restrict network access to the vulnerable /order_view.php endpoint if the functionality is not business-critical
• Implement input validation and sanitization for the transaction_id parameter at the web application firewall level
• Consider temporarily disabling the affected functionality until a proper fix can be implemented
• Review database user privileges and apply the principle of least privilege to limit potential damage

Patch Information

As of the last update on 2026-01-08, no official patch has been released by code-projects. Organizations should monitor the code-projects website for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

For additional vulnerability details, see the VulDB submission #731096 and GitHub PoC documentation.

Workarounds

• Implement parameterized queries or prepared statements in the /order_view.php file to prevent SQL injection
• Add input validation to ensure transaction_id only accepts expected numeric values
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Implement network-level access controls to restrict access to the application from untrusted networks
