CVE-2022-46443 is a high-severity SQL Injection vulnerability identified in the mesinkasir Bangresto 1.0 application. The vulnerability arises from improper sanitization of the 'itemqty[]' parameter, which allows an attacker to inject malicious SQL code. This injection flaw can be exploited remotely over the network (AV:N) with low attack complexity (AC:L) and requires low privileges (PR:L), but no user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing an attacker to read, modify, or delete sensitive data, escalate privileges, or disrupt service. The CVSS 3.1 base score is 8.8, indicating a high level of risk. Although the vendor and product details are not fully specified, the affected software is identified as mesinkasir Bangresto 1.0, which appears to be a point-of-sale or cashier system. No patches or known exploits in the wild have been reported as of the publication date (December 14, 2022). The vulnerability is classified under CWE-89, which corresponds to SQL Injection, a well-known and critical web application security issue. The vulnerability allows an attacker to execute arbitrary SQL commands by manipulating the 'itemqty[]' parameter, which could lead to unauthorized data access or manipulation, and potentially full system compromise depending on the database and application architecture.

For European organizations, especially those in retail, hospitality, or any sector utilizing mesinkasir Bangresto 1.0 or similar point-of-sale systems, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to customer payment information, inventory data, and transaction records, resulting in financial loss, reputational damage, and regulatory penalties under GDPR due to data breaches. The integrity of sales and inventory data could be compromised, affecting business operations and decision-making. Additionally, availability impacts could disrupt sales processes, causing operational downtime. Given the low complexity and network accessibility of the vulnerability, attackers could automate exploitation attempts, increasing the risk of widespread attacks. The absence of known patches heightens the urgency for mitigation. Organizations relying on this software or similar systems should consider the potential for targeted attacks, especially in countries with high retail sector digitalization or where this software is prevalent.

1. Immediate mitigation should include implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'itemqty[]' parameter. 2. Conduct thorough input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. Since no official patch is available, organizations should review and sanitize all inputs rigorously. 3. Monitor logs for unusual database query patterns or repeated failed attempts that may indicate exploitation attempts. 4. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 5. If possible, isolate the affected application from critical backend systems and sensitive data until a patch or update is available. 6. Engage with the vendor or community to obtain updates or patches and apply them promptly once released. 7. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 8. Educate development and IT teams about secure coding practices and the risks of SQL injection to prevent similar issues in future deployments.
