CVE-2025-52327 is a SQL Injection vulnerability identified in version 1.0 of the Restaurant Order System, specifically within the payment.php file. SQL Injection (SQLi) vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database query logic. In this case, a local attacker—meaning someone with access to the system or network where the application is hosted—can exploit this flaw to extract sensitive information from the backend database. The vulnerability arises because payment.php likely processes user input related to payment or order details without adequate input validation or parameterization, enabling malicious SQL code injection. Although no CVSS score has been assigned yet and no known exploits are reported in the wild, the nature of SQL Injection vulnerabilities inherently poses a significant risk to confidentiality and potentially integrity of data. The lack of patch information suggests that a fix may not yet be available, increasing the urgency for organizations using this system to implement mitigations. Since the affected version is 1.0 and no other versions are listed, it is possible this vulnerability is limited to early deployments of this software. However, given the critical role of payment processing in restaurant order systems, exploitation could lead to unauthorized access to customer payment data, order histories, or other sensitive business information stored in the database. The vulnerability requires local access, which somewhat limits the attack surface but does not eliminate risk, especially in environments where multiple users or administrators have access to the system. The absence of user interaction requirements means that once local access is obtained, exploitation can be automated or scripted. Overall, this vulnerability highlights the importance of secure coding practices, especially input validation and the use of prepared statements or parameterized queries in web applications handling sensitive financial data.

For European organizations operating restaurants or food service businesses using the vulnerable Restaurant Order System 1.0, this SQL Injection vulnerability could lead to significant data breaches involving customer payment information and order details. Such breaches can result in financial fraud, identity theft, and loss of customer trust. Additionally, compromised data could lead to regulatory penalties under GDPR due to exposure of personal and payment data. The local access requirement reduces the risk of remote exploitation but does not eliminate insider threats or risks from compromised internal accounts. The integrity of order and payment data could also be affected, potentially disrupting business operations and causing financial discrepancies. Given the critical nature of payment processing, any downtime or data corruption could impact service availability and revenue. Furthermore, the reputational damage from a breach could be severe in the competitive European market, where consumers are increasingly sensitive to data privacy and security. Organizations may also face legal liabilities and increased scrutiny from data protection authorities. The lack of a patch or workaround at present means that affected entities must rely on compensating controls to mitigate risk until a fix is available.

European organizations using the Restaurant Order System 1.0 should immediately restrict local access to the payment.php component to trusted personnel only, minimizing the attack surface. Network segmentation and strict access controls should be enforced to limit who can reach the vulnerable system. Implementing application-layer firewalls or web application firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting payment.php can provide temporary protection. Organizations should conduct thorough code reviews and penetration testing focused on input validation and database query handling in payment.php. If possible, disable or isolate the vulnerable payment processing functionality until a vendor patch is released. Monitoring database logs and application logs for unusual query patterns or access attempts can help detect exploitation attempts early. Organizations should also ensure that database accounts used by the application have the minimum necessary privileges to limit the impact of any successful injection. Finally, organizations should engage with the vendor or development team to obtain or expedite a security patch and plan for timely application once available.
