CVE-2025-11603 identifies a SQL Injection vulnerability in the Simple Food Ordering System version 1.0 developed by code-projects. The flaw exists in the /editproduct.php script where the 'Category' parameter is not properly sanitized or validated before being used in SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially manipulating the backend database. The vulnerability does not require user interaction or privileges, making it easier to exploit remotely. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack vector is network-based with low complexity and no authentication required, but with limited impact on confidentiality, integrity, and availability. The vulnerability could allow attackers to read, modify, or delete sensitive data such as product listings or user information, or disrupt service availability. Although no active exploits have been reported, the public disclosure of exploit code increases the likelihood of exploitation attempts. The absence of official patches necessitates immediate mitigation through secure coding practices, such as using prepared statements and input validation. Organizations relying on this system should audit their installations and apply compensating controls to prevent exploitation.

For European organizations using the Simple Food Ordering System, this vulnerability poses risks including unauthorized disclosure of sensitive business and customer data, data tampering, and potential service outages. Food service businesses, especially SMEs that rely on this software for order management, could suffer operational disruptions impacting revenue and customer trust. Data breaches could lead to regulatory penalties under GDPR if personal data is compromised. The attack's remote and unauthenticated nature increases the threat surface, making even less technically sophisticated attackers capable of exploitation. The impact extends beyond individual businesses to supply chain partners and customers, potentially causing reputational damage. Given the medium severity, the threat is significant but not catastrophic, yet timely mitigation is critical to avoid escalation or chaining with other vulnerabilities.

To mitigate CVE-2025-11603, organizations should immediately implement input validation and sanitization on the 'Category' parameter in /editproduct.php. Refactoring the code to use parameterized queries or prepared statements is essential to prevent SQL Injection. If source code modification is not immediately feasible, deploying Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns can provide temporary protection. Restrict database user permissions to the minimum necessary, avoiding elevated privileges that could amplify damage. Regularly monitor logs for suspicious database queries or unusual application behavior. Conduct security audits and penetration tests focusing on input handling. Engage with the vendor or community to obtain patches or updated versions. Additionally, educate developers on secure coding practices to prevent similar vulnerabilities in future releases.
