The vulnerability identified as CVE-2025-15073 affects the itsourcecode Online Frozen Foods Ordering System version 1.0. It is an SQL injection flaw located in the /contact_us.php script, specifically through manipulation of the 'Name' parameter. This vulnerability allows an unauthenticated attacker to remotely inject malicious SQL code, potentially enabling unauthorized access to or modification of the backend database. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low attack complexity and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is limited but present, as the attacker could extract sensitive data, alter database contents, or disrupt service operations. The vulnerability does not require authentication, making it accessible to any remote attacker aware of the flaw. Although no known exploits are currently active in the wild, the public disclosure of exploit details increases the risk of exploitation. The lack of available patches necessitates immediate mitigation through secure coding practices such as input sanitization and use of parameterized queries. Organizations should also audit database permissions to limit potential damage and monitor logs for suspicious activity related to the vulnerable endpoint.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized disclosure of customer data, including personal and order information, which would violate GDPR and other data protection regulations, potentially resulting in legal and financial penalties. Integrity of order data could be compromised, leading to incorrect orders or fraudulent transactions, damaging business reputation and customer trust. Availability impacts, while limited, could disrupt ordering processes, affecting revenue and operational continuity. The vulnerability's remote and unauthenticated nature increases the risk of widespread exploitation, particularly in organizations relying on the affected ordering system without adequate compensating controls. Given the critical role of e-commerce in the frozen foods sector, especially in countries with large food distribution networks, the threat could have significant operational and compliance consequences.

Immediate mitigation steps include implementing strict input validation and sanitization on the 'Name' parameter within /contact_us.php to prevent malicious SQL code injection. Refactoring the code to use parameterized queries or prepared statements is essential to eliminate SQL injection risks. Organizations should conduct a thorough code review of the entire application to identify and remediate similar vulnerabilities. Until a vendor patch is available, deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection attempts targeting the vulnerable endpoint can reduce risk. Database permissions should be minimized, ensuring the application user has only necessary privileges to limit potential damage. Continuous monitoring and logging of database queries and web requests can help detect exploitation attempts early. Additionally, organizations should prepare incident response plans specific to data breaches involving this system and ensure compliance with data breach notification requirements under GDPR.
