CVE-2025-6123 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Restaurant Order System, specifically within the /payment.php file. The vulnerability arises from improper sanitization or validation of the 'tabidNoti' parameter, which is directly used in SQL queries. An attacker can remotely exploit this flaw by manipulating the 'tabidNoti' argument to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data disclosure, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability requires no authentication or user interaction, making it highly exploitable over the network. Although the CVSS 4.0 score is 6.9 (medium severity), the nature of SQL injection vulnerabilities typically warrants close attention due to their potential impact. No patches or fixes have been published yet, and no known exploits are currently observed in the wild, but public disclosure increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which is a restaurant order management system likely used by small to medium-sized hospitality businesses to handle orders and payments online. The lack of authentication or user interaction requirements combined with remote exploitability makes this a significant threat vector for organizations using this software without mitigations in place.

For European organizations, especially those in the hospitality sector using the code-projects Restaurant Order System 1.0, this vulnerability poses a serious risk. Exploitation could lead to unauthorized access to sensitive customer payment information, order details, and potentially other backend data stored in the database. This could result in data breaches violating GDPR regulations, leading to legal penalties and reputational damage. Furthermore, attackers could manipulate order or payment data, causing financial losses or operational disruptions. Given the critical role of payment processing in restaurant operations, availability impacts could disrupt business continuity. The vulnerability's remote exploitability without authentication increases the attack surface, making it easier for threat actors to target vulnerable systems across Europe. Organizations relying on this software without timely mitigation may face increased risks of data theft, fraud, and service outages.

1. Immediate mitigation should include restricting external access to the /payment.php endpoint via network-level controls such as firewalls or web application firewalls (WAFs) with SQL injection detection and prevention capabilities. 2. Implement strict input validation and parameterized queries or prepared statements in the application code to eliminate SQL injection vectors, focusing on sanitizing the 'tabidNoti' parameter. 3. Conduct a thorough code review of the entire application to identify and remediate any other injection points or insecure coding practices. 4. Monitor logs for unusual or suspicious requests targeting the 'tabidNoti' parameter or /payment.php endpoint to detect potential exploitation attempts. 5. If possible, isolate the affected system from critical network segments until a patch or update is available. 6. Engage with the vendor or community to obtain or develop patches or updated versions that address this vulnerability. 7. Educate staff on the risks and signs of exploitation to improve incident response readiness. 8. As a longer-term measure, consider migrating to more secure and actively maintained restaurant order management platforms with robust security practices.
