CVE-2025-11603 identifies an 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 incorporated into SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion within the backend database. The vulnerability does not require user interaction or elevated privileges, increasing its exploitability. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although the impact is limited, the exploitability is straightforward due to lack of authentication and input validation. The exploit code has been publicly disclosed, increasing the risk of exploitation, though no active exploitation has been reported to date. The absence of patches or official fixes necessitates immediate mitigation efforts by users of this software. The vulnerability highlights the critical need for secure coding practices, especially input validation and use of parameterized queries in web applications handling sensitive data such as food ordering systems.

For European organizations using the Simple Food Ordering System, this vulnerability could lead to unauthorized access to sensitive customer and business data stored in the backend database. Attackers could manipulate orders, alter product information, or extract confidential data, impacting data confidentiality and integrity. Although the availability impact is low, data manipulation could disrupt business operations and damage customer trust. The food service sector, including restaurants and catering services relying on this system, may face reputational damage and regulatory scrutiny under GDPR if personal data is compromised. The medium severity suggests that while the threat is not immediately critical, it poses a tangible risk that could be exploited by attackers with minimal effort. Organizations with limited IT security resources or those using outdated versions of the software are particularly vulnerable. The public availability of exploit code increases the likelihood of opportunistic attacks, especially in countries with high adoption of this software or similar platforms.

1. Immediately implement input validation and sanitization on the 'Category' parameter in /editproduct.php to prevent SQL injection. 2. Refactor the code to use parameterized queries or prepared statements instead of directly embedding user input into SQL commands. 3. Restrict database user permissions to the minimum necessary, limiting the potential damage from successful injection attacks. 4. Monitor web application logs for suspicious activity related to the 'Category' parameter or unexpected SQL errors. 5. If patching is not available, consider deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting this endpoint. 6. Conduct a security audit of the entire application to identify and remediate similar injection vulnerabilities. 7. Educate developers on secure coding practices to prevent recurrence. 8. Regularly back up databases and ensure backups are secure to enable recovery in case of data tampering.
