CVE-2025-6483 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Simple Pizza Ordering System, specifically within the /edituser.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw by injecting crafted SQL statements through the 'ID' argument, potentially altering the intended SQL query logic executed by the backend database. This can lead to unauthorized data access, data modification, or even complete compromise of the database's integrity and confidentiality. 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 nature of SQL Injection vulnerabilities often allows attackers to escalate their privileges or pivot to further attacks, increasing the risk beyond the base score. The exploit has been publicly disclosed, raising the likelihood of active exploitation attempts. The affected product, Simple Pizza Ordering System 1.0, is a web-based application used for managing pizza orders, which may be deployed by small to medium-sized food service businesses. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls or code fixes. Given the direct impact on database queries, the vulnerability threatens the confidentiality, integrity, and availability of the underlying data store, potentially exposing sensitive customer information or disrupting business operations.

For European organizations using the Simple Pizza Ordering System 1.0, this vulnerability poses a significant risk to customer data confidentiality and business continuity. Exploitation could lead to unauthorized disclosure of personal customer information, including order details and user credentials if stored insecurely. Data integrity could be compromised by unauthorized modification or deletion of records, impacting order fulfillment and financial transactions. Availability may also be affected if attackers execute destructive queries or cause database crashes. Small and medium-sized enterprises (SMEs) in the food service sector, which often rely on off-the-shelf or open-source ordering systems, are particularly vulnerable due to limited cybersecurity resources. Additionally, compromised systems could be leveraged as entry points for broader network intrusions, threatening supply chain partners and payment processing systems. The public disclosure of the exploit increases the risk of opportunistic attacks, especially in countries with high densities of hospitality businesses. Regulatory implications under GDPR are also a concern, as data breaches involving personal data could result in significant fines and reputational damage.

1. Immediate code review and sanitization: Organizations should audit the /edituser.php script to implement parameterized queries or prepared statements for all database interactions involving user-supplied input, specifically the 'ID' parameter. 2. Input validation: Enforce strict server-side validation to ensure that 'ID' parameters conform to expected formats (e.g., numeric only) before processing. 3. Web Application Firewall (WAF): Deploy or update WAF rules to detect and block SQL injection patterns targeting the vulnerable endpoint. 4. Network segmentation: Restrict external access to the ordering system's administrative interfaces to trusted IP ranges or VPN connections. 5. Monitoring and logging: Enable detailed logging of database queries and web requests to detect anomalous activities indicative of exploitation attempts. 6. Incident response readiness: Prepare to isolate affected systems and conduct forensic analysis if exploitation is suspected. 7. Vendor engagement: Contact the vendor or community maintaining the Simple Pizza Ordering System to request official patches or updates. 8. Alternative solutions: Consider migrating to more secure, actively maintained ordering platforms if remediation is not feasible. 9. Regular backups: Maintain frequent, secure backups of the database to enable recovery in case of data tampering or loss.
