CVE-2025-7814 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Food Ordering Review System, specifically within the /pages/signup_function.php file. The vulnerability arises from improper sanitization or validation of the 'fname' parameter, which is used in SQL queries. An attacker can remotely exploit this flaw by injecting malicious SQL code through the 'fname' argument, potentially manipulating the backend database. This could allow unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium severity), the nature of SQL Injection vulnerabilities often warrants heightened attention due to their potential for severe impact. The disclosure mentions that other parameters might also be vulnerable, suggesting a broader issue with input validation in the application. No patches are currently linked, and no known exploits have been reported in the wild yet, but public disclosure means attackers could develop exploits rapidly. The vulnerability affects a niche product used for food ordering and review management, which may be deployed by restaurants or food service providers to handle customer signups and reviews.

For European organizations using the Food Ordering Review System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer data, including personally identifiable information (PII) submitted during signup. This compromises data confidentiality and may violate GDPR requirements, leading to legal and financial repercussions. Data integrity could be undermined if attackers alter or delete records, potentially disrupting business operations and damaging reputation. Availability might also be impacted if attackers execute destructive queries or cause database corruption. Given the system's role in customer interaction, service disruption could directly affect revenue and customer trust. Small to medium-sized food service businesses, which may rely on this system, often lack robust cybersecurity defenses, increasing their vulnerability. The lack of authentication or user interaction needed for exploitation means attacks can be automated and widespread. Additionally, the public disclosure of the vulnerability increases the likelihood of exploitation attempts targeting European businesses using this software.

Immediate mitigation should focus on input validation and sanitization of all user-supplied data, especially the 'fname' parameter and other potentially vulnerable inputs. Employ parameterized queries or prepared statements to prevent SQL Injection. Since no official patch is available, organizations should consider applying virtual patching via Web Application Firewalls (WAFs) configured to detect and block SQL Injection patterns targeting the signup functionality. Conduct thorough code reviews and security testing of the application to identify and remediate other injection points. Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. Monitor logs for suspicious activities related to SQL errors or unusual database queries. If feasible, consider migrating to a more secure or updated food ordering system. Finally, ensure compliance with GDPR by promptly reporting any data breaches resulting from exploitation and informing affected users.
