CVE-2026-1159 identifies a SQL injection vulnerability in the itsourcecode Online Frozen Foods Ordering System version 1.0. The vulnerability resides in the /order_online.php script, where the product_name parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. The vulnerability can lead to unauthorized access to the backend database, enabling attackers to read, modify, or delete sensitive data such as customer orders, product information, or user credentials. 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 partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no active exploitation has been reported, the public availability of an exploit increases the likelihood of attacks. The absence of patches or vendor-provided fixes at the time of publication necessitates immediate defensive measures. This vulnerability highlights the critical need for secure coding practices, particularly input validation and the use of prepared statements or parameterized queries to prevent SQL injection. Organizations relying on this software should conduct thorough code reviews and vulnerability assessments to identify and remediate similar issues.

The SQL injection vulnerability in the Online Frozen Foods Ordering System can have significant impacts on organizations worldwide. Exploitation can lead to unauthorized disclosure of sensitive customer and business data, including order details and potentially payment information, compromising confidentiality. Attackers may alter or delete data, affecting data integrity and disrupting business operations. The availability of the ordering system could be impacted if attackers execute destructive queries or cause database corruption, leading to downtime and loss of revenue. For e-commerce businesses, such breaches can damage customer trust and result in regulatory penalties, especially in regions with strict data protection laws. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, particularly if the software is deployed in multiple organizations without proper security controls. The public availability of an exploit further elevates the threat, potentially attracting opportunistic attackers and increasing the likelihood of automated scanning and exploitation attempts.

To mitigate CVE-2026-1159, organizations should immediately implement the following specific measures: 1) Apply vendor patches or updates as soon as they become available. 2) If patches are unavailable, modify the /order_online.php code to use parameterized queries or prepared statements for all database interactions involving user input, especially the product_name parameter. 3) Implement strict input validation and sanitization to reject or escape malicious input patterns. 4) Restrict database user permissions to the minimum necessary, preventing unauthorized data modification or access. 5) Employ web application firewalls (WAFs) with rules targeting SQL injection patterns to provide an additional layer of defense. 6) Conduct regular security code reviews and penetration testing focused on injection flaws. 7) Monitor logs for unusual database queries or error messages indicative of injection attempts. 8) Educate developers on secure coding practices to prevent similar vulnerabilities in future releases. 9) Consider isolating the ordering system database from other critical systems to limit lateral movement in case of compromise. 10) Maintain an incident response plan to quickly address any detected exploitation attempts.
