CVE-2025-5319 is a critical SQL Injection vulnerability (CWE-89) identified in the Efficiency Management System produced by Emit Information and Communication Technologies Industry and Trade Ltd. Co. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to inject malicious SQL code. This can lead to unauthorized data access, data modification, or complete system compromise. The vulnerability is remotely exploitable over the network without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The CVSS score of 9.8 reflects the critical nature of this flaw, impacting confidentiality, integrity, and availability. The vendor has not responded to disclosure attempts, and no patches are currently available, leaving systems exposed. The affected product version is listed as '0' through 03022026, suggesting either an early or default versioning scheme. SQL Injection vulnerabilities typically allow attackers to bypass authentication, extract sensitive data, corrupt databases, or execute administrative operations on the database server. Given the product’s role in efficiency management, exploitation could disrupt business operations and leak sensitive corporate data. The lack of known exploits in the wild does not diminish the urgency, as public disclosure without remediation often leads to rapid exploitation attempts. The vulnerability demands immediate attention from organizations using this system to prevent potential breaches.

For European organizations, the impact of CVE-2025-5319 could be severe. The Efficiency Management System likely handles critical operational data, and exploitation could lead to unauthorized disclosure of sensitive business information, manipulation of operational parameters, or denial of service. This could result in financial losses, reputational damage, regulatory penalties under GDPR due to data breaches, and operational disruptions. Industries relying heavily on efficiency management software, such as manufacturing, logistics, and utilities, may experience cascading effects impacting supply chains and service delivery. The absence of vendor patches increases the risk window, potentially inviting attackers to develop and deploy exploits. Additionally, the critical severity and ease of exploitation mean attackers can compromise systems without credentials or user interaction, increasing the threat to organizations with internet-facing instances of the software. European entities with compliance obligations must also consider the legal ramifications of data breaches stemming from this vulnerability.

Given the lack of vendor patches, European organizations should implement immediate compensating controls. First, restrict network access to the Efficiency Management System by limiting exposure to trusted internal networks or VPNs. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this system. Conduct thorough input validation and sanitization at the application layer if source code access is available, replacing dynamic SQL queries with parameterized prepared statements. Monitor logs for suspicious database query patterns or unusual application behavior indicative of injection attempts. Regularly back up databases and ensure backups are stored securely offline to enable recovery in case of compromise. Engage in threat hunting and incident response preparedness focused on this vulnerability. If feasible, consider migrating to alternative solutions or isolating the affected system until a vendor patch or official fix is released. Coordinate with cybersecurity information sharing groups to stay updated on emerging exploits or mitigation techniques.
