CVE-2022-43352 is a high-severity SQL injection vulnerability identified in the Sanitization Management System version 1.0. The vulnerability exists in the 'id' parameter of the endpoint /php-sms/classes/Master.php?f=delete_quote. SQL injection (CWE-89) vulnerabilities allow an attacker to manipulate backend SQL queries by injecting malicious SQL code through unsanitized input parameters. In this case, the 'id' parameter is not properly sanitized, enabling an attacker with high privileges (PR:H) to execute arbitrary SQL commands remotely over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the system, allowing an attacker to read, modify, or delete sensitive data, or potentially disrupt system operations. The CVSS 3.1 base score of 7.2 reflects the significant risk posed by this vulnerability. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a critical concern for affected organizations. The lack of vendor or product-specific information limits precise identification, but the vulnerability is tied to a web-based management system used for sanitization processes, which may be deployed in healthcare, manufacturing, or environmental services sectors.

For European organizations, exploitation of this SQL injection vulnerability could lead to severe consequences including unauthorized access to sensitive data, data corruption, or complete denial of service of the Sanitization Management System. Given the system's likely role in managing sanitization workflows, compromised integrity or availability could disrupt critical operational processes, potentially affecting compliance with EU data protection regulations such as GDPR if personal or sensitive data is involved. The confidentiality breach risk could expose proprietary or personal information, leading to reputational damage and regulatory penalties. Additionally, attackers could leverage this vulnerability as a foothold to pivot within the network, escalating privileges or deploying ransomware. The high privilege requirement reduces the attack surface somewhat, but insider threats or compromised credentials could still enable exploitation. The absence of known exploits suggests organizations have a window to remediate before active attacks emerge.

Organizations should immediately audit their use of the Sanitization Management System to identify affected instances. Given the absence of vendor patches, mitigation should focus on implementing strict input validation and parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) can be configured to detect and block SQL injection attempts targeting the 'id' parameter at the specified endpoint. Access controls should be reviewed to minimize the number of users with high privileges capable of exploiting this vulnerability. Network segmentation and monitoring for unusual database queries or application behavior can help detect exploitation attempts early. Additionally, organizations should consider deploying runtime application self-protection (RASP) tools to provide real-time protection. Regular backups and incident response plans should be updated to prepare for potential data integrity or availability incidents. Finally, organizations should engage with the vendor or community to obtain or develop patches and monitor threat intelligence sources for emerging exploits.
