CVE-2025-6481 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Simple Pizza Ordering System, specifically affecting the /update.php endpoint. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data disclosure, data modification, or even deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability does not require any authentication or user interaction, making it exploitable by any remote attacker with network access to the affected system. Although the CVSS 4.0 score is 6.9 (medium severity), the classification as critical in the description suggests that the impact could be significant, especially given the ease of exploitation and the lack of required privileges. No patches or fixes have been published yet, and no known exploits are currently in the wild, but public disclosure of the exploit code increases the risk of imminent attacks. The vulnerability affects only version 1.0 of the Simple Pizza Ordering System, which is a niche product likely used by small to medium-sized food service businesses for order management.

For European organizations, the impact of this vulnerability depends largely on the adoption of the Simple Pizza Ordering System within the region. If deployed, exploitation could lead to unauthorized access to customer data, order details, and potentially payment information stored in the backend database. This could result in data breaches violating GDPR regulations, leading to legal penalties and reputational damage. Additionally, attackers could manipulate or delete order data, disrupting business operations and causing financial loss. Given the remote and unauthenticated nature of the exploit, attackers could easily target multiple installations en masse. Small and medium enterprises (SMEs) in the food service sector, which may lack robust cybersecurity defenses, are particularly at risk. The vulnerability also poses a risk to supply chain integrity if the ordering system interfaces with other internal systems. However, the limited scope to a specific product and version somewhat restricts the overall impact across Europe.

1. Immediate mitigation should involve restricting external access to the /update.php endpoint through network-level controls such as firewalls or web application firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'ID' parameter. 2. Implement input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. Since no official patch is available, organizations should review and modify the source code to sanitize inputs properly. 3. Conduct a thorough audit of all instances of the Simple Pizza Ordering System version 1.0 within the organization to identify affected systems. 4. Monitor logs for suspicious activities related to the /update.php endpoint, especially unusual query strings or error messages indicative of injection attempts. 5. If feasible, isolate the affected system from critical internal networks to limit lateral movement in case of compromise. 6. Educate IT and security teams about this specific vulnerability and the importance of timely patching or code remediation once updates become available. 7. Plan for migration to a newer, secure version of the software or consider alternative ordering systems with better security postures.
