PHP RCE (CVE-2026-30532)

Overview

A critical security vulnerability, identified as CVE-2026-30532, has been discovered in the SourceCodester Online Food Ordering System version 1.0. This flaw is a SQL Injection (SQLi) vulnerability located in the admin/view_product.php file. Attackers can exploit it by manipulating the “id” parameter, potentially leading to a full compromise of the application’s database and admin panel.

Vulnerability Details

In simple terms, this vulnerability exists because the application does not properly sanitize or validate user input before using it in a database query. Specifically, when the system fetches product details for the administrator to view, the “id” value received from the user’s request is directly incorporated into a SQL command without adequate checks.

An attacker can craft a malicious request containing SQL code within this “id” parameter. When processed, the database executes this injected code as if it were a legitimate part of the intended command. This type of flaw is a classic and highly dangerous form of attack on web applications.

Potential Impact

The impact of this vulnerability is severe, earning a maximum CVSS score of 9.8 (CRITICAL). Successful exploitation can allow an unauthenticated remote attacker to:

• Read, modify, or delete sensitive data from the database, including customer information, order details, and administrative credentials.
• Bypass authentication and gain unauthorized administrative access to the system’s backend.
• Potentially achieve remote code execution on the underlying server, depending on the database configuration and permissions.

This could lead to a complete system takeover, data theft, and website defacement. For context on the real-world damage of such breaches, you can review historical incidents in our breach reports.

Remediation and Mitigation

Immediate action is required for all users of SourceCodester Online Food Ordering System v1.0.

Primary Remediation:

1. Patch or Update: Contact the vendor (SourceCodester) immediately to obtain a patched version of the software. If a patch is available, apply it without delay. Replace all existing v1.0 installations with the updated, secure version.
2. Code Fix: If you must modify the code directly, ensure all user inputs (especially the “id” parameter in admin/view_product.php) are properly sanitized. Use prepared statements with parameterized queries, which is the strongest defense against SQL Injection.

Temporary Mitigation (if patching is delayed):

• Implement a Web Application Firewall (WAF) configured to block SQL Injection patterns.
• Restrict access to the /admin/ directory to only trusted IP addresses, if possible.
• Closely monitor database and application logs for any suspicious query activity.
