CVE-2022-44296 is a high-severity SQL Injection vulnerability affecting Sanitization Management System version 1.0. The vulnerability exists in the web application component located at the endpoint /php-sms/admin/quotes/manage_remark.php, specifically in the handling of the 'id' parameter. An attacker can inject malicious SQL code through this parameter due to insufficient input sanitization and validation, allowing unauthorized manipulation of the backend database. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). According to the CVSS 3.1 vector, the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The impact scope is unchanged (S:U), but the confidentiality, integrity, and availability of the affected system are all rated high (C:H/I:H/A:H). This means a successful exploit could lead to full compromise of the database, including unauthorized data disclosure, data modification, or deletion, and potentially disruption of service. No official patch or vendor information is currently available, and no known exploits have been reported in the wild. The vulnerability was reserved on 2022-10-30 and published on 2022-11-30. The lack of vendor and product details limits precise identification of affected deployments, but the presence of a web-based management system for sanitization processes suggests use in healthcare, industrial hygiene, or facility management environments where sanitization tracking is critical.

For European organizations, this vulnerability poses a significant risk especially to entities involved in healthcare, public health, sanitation services, and facility management that may use Sanitization Management System v1.0 or similar software. Exploitation could lead to unauthorized access to sensitive operational data, including sanitization schedules, personnel records, or compliance documentation. This could result in regulatory non-compliance under GDPR due to exposure of personal or operational data. Integrity compromise could allow attackers to falsify sanitization records, potentially endangering public health or safety. Availability impacts could disrupt critical sanitization workflows, affecting hospitals, public transport, or manufacturing plants. Given the high privileges required for exploitation, insider threats or compromised administrative accounts are likely attack vectors. The absence of patches increases the window of exposure. The impact is exacerbated in sectors where sanitization is tightly regulated and critical for operational continuity, such as healthcare facilities, food production, and public infrastructure.

1. Immediate mitigation should focus on restricting access to the vulnerable endpoint (/php-sms/admin/quotes/manage_remark.php) to trusted administrative users only, ideally through network segmentation and firewall rules limiting access by IP or VPN. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'id' parameter. 3. Conduct thorough input validation and sanitization on all parameters, especially 'id', using parameterized queries or prepared statements to prevent injection. 4. Monitor logs for unusual database queries or failed login attempts that could indicate exploitation attempts. 5. Enforce strict privilege management to minimize the number of users with high-level access (PR:H) required to exploit this vulnerability. 6. If possible, isolate the affected system from the internet or untrusted networks until a patch or vendor guidance is available. 7. Perform regular security audits and penetration testing focused on injection vulnerabilities in web applications. 8. Engage with the software provider or community to obtain updates or patches and apply them promptly once available. 9. Educate administrators on the risks of SQL injection and the importance of secure coding and configuration practices.
