CVE-2026-7409: Pizzafy Ecommerce System SQLi Vulnerability

CVE-2026-7409 Overview

A SQL injection vulnerability has been discovered in SourceCodester Pizzafy Ecommerce System version 1.0. The flaw exists in the save_user function within the /admin/ajax.php?action=save_user endpoint. Attackers can manipulate input parameters to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. The vulnerability can be exploited remotely, and an exploit has been published publicly.

Critical Impact

Remote attackers with administrative privileges can exploit this SQL injection vulnerability to manipulate database queries, potentially accessing, modifying, or deleting sensitive user and order data within the Pizzafy ecommerce platform.

Affected Products

• SourceCodester Pizzafy Ecommerce System 1.0
• /admin/ajax.php endpoint (specifically the save_user function)

Technical Details for CVE-2026-7409

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the administrative user management functionality of the Pizzafy Ecommerce System. The save_user function processes user-supplied input without proper sanitization or parameterized queries, allowing attackers to inject malicious SQL statements into database queries.

The exploitation requires network access to the target system and administrative privileges within the application. While the impact is constrained due to the requirement for authenticated admin access, successful exploitation could still result in unauthorized data disclosure, data integrity violations, and potential disruption of the ecommerce platform's user management capabilities.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and sanitization within the save_user function. The application directly incorporates user-supplied data into SQL queries without using parameterized statements or prepared queries, enabling injection attacks. This is a classic example of CWE-74, where special characters in user input are not properly neutralized before being used in SQL operations.

Attack Vector

The attack is network-based and targets the /admin/ajax.php?action=save_user endpoint. An attacker with administrative access to the Pizzafy application can craft malicious requests containing SQL injection payloads. When the save_user function processes these requests, the injected SQL commands are executed against the backend database.

The vulnerability allows authenticated administrators (or attackers who have compromised admin credentials) to manipulate the SQL queries used for user management operations. This could enable extraction of sensitive data, modification of user records, or escalation within the database context. For detailed technical exploitation information, see the GitHub Exploit Documentation.

Detection Methods for CVE-2026-7409

Indicators of Compromise

• Unusual or malformed HTTP requests to /admin/ajax.php?action=save_user containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Database error messages appearing in application logs indicating syntax errors or unexpected query behavior
• Unexpected database modifications to user records or access patterns that deviate from normal administrative operations

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in requests to the admin panel endpoints
• Enable detailed logging for the /admin/ajax.php endpoint and monitor for suspicious parameter values containing SQL metacharacters
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access attempts originating from the web application

Monitoring Recommendations

• Review web server access logs for repeated or automated requests to the vulnerable endpoint with varying payload patterns
• Monitor database audit logs for queries containing unexpected SQL statements or operations that deviate from the application's normal query patterns
• Establish baseline behavior for administrative user management activities and alert on deviations that could indicate exploitation attempts

How to Mitigate CVE-2026-7409

Immediate Actions Required

• Restrict access to the administrative panel (/admin/) to trusted IP addresses only until a patch is applied
• Implement a Web Application Firewall with SQL injection protection rules targeting the vulnerable endpoint
• Review database user privileges to ensure the application uses a least-privilege account that limits the impact of potential SQL injection
• Audit administrative accounts for unauthorized access and rotate credentials if compromise is suspected

Patch Information

No official patch information is currently available from SourceCodester for this vulnerability. Organizations should monitor the SourceCodester Resource Page for updates and security advisories. In the meantime, implementing the workarounds and detection strategies outlined above is strongly recommended.

For additional vulnerability details and community tracking, see the VulDB Vulnerability #360143 entry.

Workarounds

• Implement prepared statements and parameterized queries in the save_user function to prevent SQL injection
• Deploy input validation that whitelists allowed characters and rejects requests containing SQL metacharacters
• Consider disabling or restricting the affected functionality until proper code remediation can be implemented
• Use a reverse proxy or WAF to filter malicious requests before they reach the application

# Example: Restrict admin panel access via Apache .htaccess
# Add to /admin/.htaccess to limit access by IP
<RequireAll>
    Require ip 10.0.0.0/8
    Require ip 192.168.1.0/24
</RequireAll>
