PHP RCE (CVE-2026-30533)

Overview

A critical SQL Injection (SQLi) vulnerability has been discovered in SourceCodester Online Food Ordering System version 1.0. Tracked as CVE-2026-30533, this flaw resides in the admin/manage_product.php file and allows unauthenticated attackers to execute malicious database commands. This vulnerability poses a severe risk to any restaurant or business using this software.

Vulnerability Details

The vulnerability is located in the “id” parameter of the product management page within the admin panel. Due to insufficient input validation, an attacker can craft special requests containing SQL code. When processed by the system, this malicious code tricks the database into executing unintended commands. This type of attack can be performed remotely without requiring prior login credentials, making it highly exploitable.

Potential Impact

The impact of this vulnerability is severe. Successful exploitation could allow an attacker to:

• Steal sensitive data from the database, including customer information, order details, and administrator credentials.
• Modify, delete, or corrupt database contents, disrupting business operations.
• Potentially gain full control over the web application and the underlying server, depending on database permissions. This could lead to significant data breaches, financial loss, and reputational damage. For examples of how such vulnerabilities lead to incidents, you can review recent data breach reports at breach reports.

Remediation and Mitigation

Immediate action is required to secure affected systems.

Primary Remediation:

1. Patch or Upgrade: Contact the software vendor (SourceCodester) immediately to obtain a patched version of the software. There is no official patch for v1.0 at this advisory’s publication; upgrading to a newer, supported version is strongly recommended.
2. Apply the Fix: Replace the vulnerable manage_product.php file with the patched version from the vendor. Ensure all associated files are updated.

Temporary Mitigation: If an immediate patch cannot be applied, consider these temporary measures:

• Input Validation: Implement strict server-side validation and sanitization for all user inputs, especially the “id” parameter. Use parameterized queries or prepared statements, which is the most effective defense against SQL Injection.
• Web Application Firewall (WAF): Deploy a WAF with rules configured to block SQL injection patterns. This can help filter malicious traffic but is not a substitute for patching.
• Network Restriction: Restrict access to the admin panel (e.g., /admin/) to known, trusted IP addresses only.
