CVE-2026-7393: Pizzafy Ecommerce System RCE Vulnerability

CVE-2026-7393 Overview

A vulnerability was found in SourceCodester Pizzafy Ecommerce System 1.0 affecting the save_menu function within the /admin/admin_class_novo.php file. The File Extension Handler component fails to properly validate uploaded file types, allowing manipulation of the img argument to achieve unrestricted file upload. This vulnerability can be exploited remotely and a public exploit is available.

Critical Impact

Unrestricted file upload vulnerability allows attackers with administrative privileges to upload arbitrary files, potentially leading to remote code execution on vulnerable systems.

Affected Products

• SourceCodester Pizzafy Ecommerce System 1.0
• Systems running the affected /admin/admin_class_novo.php component
• Servers with the vulnerable File Extension Handler implementation

Technical Details for CVE-2026-7393

Vulnerability Analysis

This vulnerability is classified under CWE-284 (Improper Access Control), though the core issue relates to unrestricted file upload functionality. The save_menu function in the administrative panel does not implement proper file type validation when processing the img parameter. This allows an authenticated administrator to upload files with arbitrary extensions, bypassing any intended restrictions on allowed file types.

The vulnerability exists in the file upload handling mechanism where the application fails to validate or sanitize the file extension before storing uploaded content. Without proper validation, an attacker could upload a malicious PHP web shell or other executable content that could then be accessed and executed on the server.

Root Cause

The root cause lies in the improper implementation of file upload validation within the save_menu function. The application does not enforce a whitelist of acceptable file extensions, nor does it validate the actual content type of uploaded files. This allows any file type to be uploaded through the img parameter, regardless of whether it matches expected image formats.

Attack Vector

The attack is network-based and requires authentication with administrative privileges to the Pizzafy Ecommerce System. An attacker with valid admin credentials can exploit this vulnerability by:

1. Accessing the menu management functionality in the admin panel
2. Uploading a malicious file (such as a PHP web shell) through the image upload feature
3. Accessing the uploaded file directly to execute arbitrary code on the server

The vulnerability mechanism involves manipulating the img parameter during the menu save operation. When a file is uploaded without proper extension validation, an attacker can submit a PHP file disguised with any filename. Once uploaded to the server, accessing this file directly triggers server-side execution. For detailed technical analysis, see the GitHub PoC Repository and VulDB entry.

Detection Methods for CVE-2026-7393

Indicators of Compromise

• Unexpected file types (PHP, ASP, JSP) appearing in image upload directories
• Web shell signatures or unusual PHP files in /uploads/ or similar directories
• Anomalous HTTP requests to recently uploaded files with executable extensions
• Administrative account activity showing unusual file upload patterns

Detection Strategies

• Monitor file upload directories for non-image file extensions being written
• Implement file integrity monitoring on web application directories
• Review web server access logs for requests to unusual files in upload paths
• Deploy web application firewall rules to detect malicious file upload attempts

Monitoring Recommendations

• Enable logging for all administrative actions in the Pizzafy Ecommerce System
• Configure alerts for file creation events with executable extensions in web directories
• Monitor outbound network connections from the web server for potential reverse shell activity
• Implement real-time file type analysis for uploaded content

How to Mitigate CVE-2026-7393

Immediate Actions Required

• Restrict access to administrative functions until patching is complete
• Review and audit all files in upload directories for suspicious content
• Implement network-level restrictions limiting admin panel access to trusted IPs
• Consider temporarily disabling file upload functionality if feasible

Patch Information

No official vendor patch information is available at this time. Administrators should monitor SourceCodester for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

Workarounds

• Implement server-side file extension whitelist validation allowing only image formats (jpg, jpeg, png, gif)
• Add MIME type validation to verify uploaded content matches declared file type
• Configure web server to prevent execution of scripts in upload directories
• Rename uploaded files with generated names, removing original extensions
• Store uploaded files outside the web root where possible

# Apache configuration to prevent script execution in uploads directory
<Directory "/var/www/html/uploads">
    Options -ExecCGI -Indexes
    AllowOverride None
    <FilesMatch "\.(php|phtml|php3|php4|php5|pl|py|jsp|asp|aspx|cgi|sh)$">
        Require all denied
    </FilesMatch>
</Directory>
