CVE-2025-13571 identifies a SQL Injection vulnerability in the Simple Food Ordering System version 1.0 developed by code-projects. The flaw exists in the /listorder.php script where the 'ID' parameter is not properly sanitized or validated before being used in SQL queries. This allows an unauthenticated remote attacker to inject malicious SQL code by manipulating the 'ID' argument, potentially enabling unauthorized access to the backend database. The vulnerability does not require user interaction or authentication, which lowers the barrier for exploitation. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L but likely a typo or low privilege), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation. The vulnerability could allow attackers to extract sensitive order data, modify or delete records, or escalate privileges within the application. The absence of patches or vendor advisories necessitates immediate mitigation by users. The vulnerability is typical of insufficient input validation and lack of parameterized queries, common issues in web applications handling user inputs.

For European organizations, particularly those in the food service, hospitality, and small to medium enterprise sectors using the affected Simple Food Ordering System, this vulnerability poses a risk of data breaches involving customer orders, payment information, and business operations data. Exploitation could lead to unauthorized data disclosure, data manipulation, or denial of service, undermining customer trust and potentially violating GDPR requirements regarding data protection. The medium severity reflects limited but tangible risks to confidentiality, integrity, and availability. Given the remote exploitability without authentication, attackers could target multiple organizations en masse. Disruption of order processing systems could impact business continuity and revenue. Additionally, compromised systems could serve as pivot points for broader network intrusion. The lack of known exploits currently reduces immediate risk but does not eliminate it, especially as exploit code may emerge following public disclosure.

Organizations should immediately audit their use of the Simple Food Ordering System version 1.0 and isolate affected instances. Since no official patches are available, implement the following mitigations: 1) Apply strict input validation and sanitization on the 'ID' parameter in /listorder.php to reject malicious input patterns. 2) Refactor database queries to use parameterized prepared statements or stored procedures to prevent SQL injection. 3) Restrict database user privileges to the minimum necessary, avoiding excessive rights that could be exploited. 4) Monitor web application logs for suspicious query patterns or repeated attempts to manipulate the 'ID' parameter. 5) Employ Web Application Firewalls (WAFs) with rules targeting SQL injection attempts to provide an additional protective layer. 6) Consider migrating to updated or alternative food ordering systems with active security support. 7) Conduct security awareness training for developers and administrators on secure coding practices. 8) Regularly back up databases and test restoration procedures to mitigate data loss risks.
