CVE-2022-43330 is a high-severity SQL injection vulnerability identified in Canteen Management System version 1.0. The vulnerability exists in the /editorder.php endpoint, specifically via the 'id' parameter. SQL injection (CWE-89) vulnerabilities allow an attacker to manipulate backend SQL queries by injecting malicious input, potentially leading to unauthorized data access, data modification, or even full system compromise. According to the CVSS 3.1 vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), the attack requires network access with low attack complexity but does require high privileges (PR:H) and no user interaction. The scope is unchanged, but the impact on confidentiality, integrity, and availability is high, indicating that successful exploitation could lead to full compromise of the affected system's data and functionality. No patches or vendor information are currently provided, and no known exploits in the wild have been reported. The vulnerability was published on November 1, 2022, and is recognized by CISA enrichment, indicating its significance in cybersecurity advisories.

For European organizations using the Canteen Management System v1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive order and user data, manipulation of order records, and disruption of canteen operations. This could result in data breaches violating GDPR requirements, financial losses, reputational damage, and operational downtime. Given the high privileges required, exploitation might be limited to insiders or attackers who have already gained elevated access, but the network accessibility means lateral movement within an organization's network could be facilitated. Organizations in sectors with critical infrastructure or public services relying on such systems could face amplified consequences, including service interruptions and regulatory penalties.

To mitigate this vulnerability, organizations should immediately audit their use of the Canteen Management System v1.0 and isolate affected instances from the network where possible. Since no official patch is currently available, applying web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the 'id' parameter in /editorder.php is recommended. Conduct thorough input validation and parameterized queries or prepared statements in the application code to prevent injection. Restrict database user privileges to the minimum necessary to limit potential damage. Monitor logs for suspicious activity related to the editorder.php endpoint. Additionally, implement network segmentation to limit access to the vulnerable system and enforce strict access controls to reduce the risk posed by the high privilege requirement. Organizations should also engage with the vendor or developer for patches or updates and plan for timely application once available.
