SQL Injection in CodeAstro Ecommerce Website

Executive Summary

CVE-2026-14767 is a critical SQL injection vulnerability found in CodeAstro Ecommerce Website version 1.0. It exists in the /ecommerce-website-php/customer/confirm.php file, specifically in the invoice_no parameter of the payment confirmation form.

The vulnerability occurs because the invoice_no parameter is directly concatenated into SQL queries without proper sanitization or parameterized binding. This allows attackers to inject malicious SQL payloads remotely, even with low-privilege session access.

Attackers can exploit this flaw to execute arbitrary SQL commands, potentially extracting sensitive data, modifying or deleting data, or gaining full control over the system.

Detection Guidance

This vulnerability can be detected by testing the invoice_no parameter in the /ecommerce-website-php/customer/confirm.php file for SQL injection flaws. A common approach is to use automated tools like sqlmap to perform time-based blind SQL injection tests against this parameter.

• Use sqlmap with a command similar to: sqlmap -u "http://targetsite/ecommerce-website-php/customer/confirm.php" --data="invoice_no=1" --time-sec=5 --technique=T
• Monitor network traffic for suspicious SQL injection payloads targeting the invoice_no parameter.

Mitigation Strategies

Immediate mitigation steps include implementing prepared statements with parameter binding to prevent SQL injection, enforcing strict input validation on the invoice_no parameter, and applying the principle of least privilege for database accounts used by the application.

• Replace direct concatenation of invoice_no in SQL queries with parameterized queries.
• Validate and sanitize all user inputs, especially invoice_no, to allow only expected formats.
• Limit database user permissions to only what is necessary for the application.
• Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
