CVE-2025-10400 is a medium-severity SQL Injection vulnerability identified in version 1.0 of the SourceCodester Food Ordering Management System. The vulnerability exists in an unspecified function within the /routers/ticket-message.php file, specifically involving the manipulation of the 'ticket_id' parameter. An attacker can exploit this flaw remotely without requiring user interaction or elevated privileges, by crafting malicious input to the 'ticket_id' argument. This input is improperly sanitized or validated, allowing the attacker to inject arbitrary SQL commands into the backend database query. Such SQL Injection attacks can lead to unauthorized data access, data modification, or even deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. The CVSS 4.0 base score is 5.3, reflecting a medium impact with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability affects only version 1.0 of the product, and no official patches or fixes have been published yet. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability's scope is limited to the Food Ordering Management System, which is typically used by restaurants or food service providers to manage orders and customer tickets. Exploitation could allow attackers to access sensitive customer data, order details, or internal ticketing information, potentially leading to data breaches or disruption of service.

For European organizations using the SourceCodester Food Ordering Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer and order data. Food service providers often handle sensitive personal information, including customer names, contact details, and payment information. Successful exploitation could lead to unauthorized data disclosure, impacting customer privacy and potentially violating GDPR regulations. Additionally, attackers could manipulate order or ticket data, causing operational disruptions, financial losses, and reputational damage. The remote exploitability without authentication increases the threat level, especially for organizations that expose the vulnerable system to the internet or have insufficient network segmentation. Given the critical role of food ordering systems in business operations, any downtime or data compromise could affect service continuity and customer trust. Furthermore, the lack of available patches means organizations must rely on mitigation strategies to reduce exposure until an official fix is released.

European organizations should implement the following specific mitigation measures: 1) Immediately restrict external access to the vulnerable /routers/ticket-message.php endpoint by applying network-level controls such as firewalls or web application firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'ticket_id' parameter. 2) Conduct a thorough code review and apply input validation and parameterized queries or prepared statements for all database interactions involving user-supplied input, especially the 'ticket_id' parameter, to prevent injection attacks. 3) If possible, upgrade or replace the vulnerable Food Ordering Management System with a patched or alternative solution that addresses this vulnerability. 4) Monitor application logs and database logs for suspicious activities indicative of SQL injection attempts, such as unusual query patterns or errors. 5) Implement strict access controls and network segmentation to isolate the food ordering system from sensitive internal networks and limit the blast radius of a potential compromise. 6) Educate IT and security teams about this vulnerability and ensure incident response plans include steps for SQL injection detection and remediation. 7) Regularly back up critical data and verify backup integrity to enable recovery in case of data corruption or deletion caused by exploitation.
