CVE-2025-12504 is a critical SQL Injection vulnerability identified in Talent Software's UNIS product, affecting all versions prior to 42321. The vulnerability stems from improper neutralization of special elements in SQL commands (CWE-89), which allows attackers to inject malicious SQL code. This can be exploited remotely over the network without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Successful exploitation can lead to full compromise of the backend database, resulting in unauthorized data disclosure, data modification, or deletion, and potentially complete system takeover. The vulnerability's critical CVSS score of 9.8 reflects its high impact on confidentiality, integrity, and availability. Although no public exploits are currently reported, the nature of SQL Injection vulnerabilities makes them attractive targets for attackers. The lack of available patches at the time of disclosure increases the urgency for organizations to implement interim mitigations. Given the widespread use of UNIS in various sectors, this vulnerability poses a significant risk, especially where sensitive or critical data is managed.

For European organizations, exploitation of this vulnerability could lead to severe data breaches, loss of data integrity, and service disruptions. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on Talent Software UNIS could face operational downtime and regulatory penalties under GDPR due to data exposure. The ability to execute arbitrary SQL commands remotely without authentication increases the risk of widespread compromise. Attackers could exfiltrate sensitive personal data, intellectual property, or manipulate records, undermining trust and causing financial and reputational damage. Additionally, the potential for complete system compromise could facilitate further lateral movement within networks, escalating the threat landscape. The absence of known exploits currently provides a window for proactive defense, but the critical severity demands immediate attention to prevent exploitation in Europe’s highly regulated and data-sensitive environment.

European organizations should immediately inventory their deployments of Talent Software UNIS to identify affected versions. Until an official patch is released, implement strict input validation and sanitization on all user inputs interacting with the database to prevent injection of malicious SQL commands. Employ Web Application Firewalls (WAFs) with SQL Injection detection and blocking capabilities tailored to the UNIS application’s traffic patterns. Monitor database and application logs for unusual queries or access patterns indicative of exploitation attempts. Restrict network access to the UNIS application to trusted IP ranges and enforce least privilege principles on database accounts used by the application. Prepare for rapid deployment of official patches once available by establishing a tested update process. Additionally, conduct security awareness training for administrators and developers on secure coding practices to prevent similar vulnerabilities. Engage in threat hunting activities to detect any early exploitation attempts within the network.
