CVE-2026-1159 is a SQL Injection vulnerability affecting itsourcecode Online Frozen Foods Ordering System version 1.0. The vulnerability resides in the /order_online.php script, specifically in the processing of the product_name parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, which the backend database executes. This can lead to unauthorized access to sensitive data, data corruption, or even full compromise of the database server. The vulnerability requires no authentication or user interaction, making it highly accessible for attackers. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The lack of patches or official remediation at the time of publication necessitates immediate defensive measures. This vulnerability is typical of improper input sanitization and lack of parameterized queries in web applications, a common and critical security flaw in e-commerce platforms.

For European organizations using the itsourcecode Online Frozen Foods Ordering System, this vulnerability poses significant risks including unauthorized disclosure of customer data, manipulation or deletion of order information, and potential disruption of online ordering services. Such impacts can lead to financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. The remote and unauthenticated nature of the exploit increases the attack surface, potentially allowing widespread exploitation if the software is widely deployed. Given the critical role of e-commerce in the frozen foods sector, especially in countries with high online grocery penetration, the vulnerability could affect supply chain reliability and customer trust. Additionally, attackers could leverage the compromised system as a foothold for further network intrusion. The medium severity rating reflects the balance between ease of exploitation and the limited but meaningful impact on confidentiality, integrity, and availability.

European organizations should immediately implement input validation and sanitization on the product_name parameter to prevent SQL injection. Employing parameterized queries or prepared statements in the /order_online.php script is essential to eliminate direct SQL command injection. Until an official patch is released, consider deploying Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns on the affected endpoint. Conduct thorough code reviews and penetration testing focused on SQL injection vectors in the ordering system. Restrict database user permissions to the minimum necessary to limit damage in case of exploitation. Monitor logs for suspicious query patterns or repeated failed attempts targeting product_name. If feasible, isolate the ordering system from critical internal networks to contain potential breaches. Finally, maintain up-to-date backups of the database to enable recovery from data corruption or deletion attacks.
