CVE-2025-54946 is a critical SQL injection vulnerability identified in the SUNNET Technology Co., Ltd. Corporate Training Management System versions prior to 10.11. This vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing remote attackers to inject arbitrary SQL code. Exploitation does not require authentication, user interaction, or privileges, and can be performed remotely over the network. The vulnerability enables attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, data modification, or deletion, and possibly full system compromise depending on database privileges. The CVSS 4.0 base score is 9.3, reflecting its critical severity with high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects the Corporate Training Management System, which is used for managing corporate training activities, user data, and possibly sensitive employee information. The lack of input validation or parameterized queries in the affected versions allows attackers to manipulate SQL queries directly, posing a severe risk to data security and system stability.

For European organizations using SUNNET's Corporate Training Management System, this vulnerability presents a significant risk. Exploitation could lead to unauthorized disclosure of sensitive employee and corporate training data, impacting confidentiality. Integrity of training records and user data could be compromised, leading to misinformation or fraudulent records. Availability of the system could be disrupted through destructive SQL commands or database corruption. Given the critical CVSS score and the absence of required authentication, attackers could easily exploit this vulnerability remotely, increasing the risk of widespread attacks. Organizations in sectors with strict data protection regulations such as GDPR could face legal and compliance repercussions if sensitive personal data is exposed. Additionally, disruption of training systems could impact employee development and operational continuity. The threat is heightened for organizations that have integrated this system deeply into their HR and compliance workflows.

Immediate mitigation should focus on applying vendor patches once available. In the absence of patches, organizations should implement web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the Corporate Training Management System. Input validation and sanitization should be enforced at the application layer, ensuring all user-supplied data is properly escaped or parameterized before database queries. Network segmentation can limit exposure by restricting access to the training system to trusted internal networks only. Regular security assessments and penetration testing should be conducted to identify and remediate injection points. Monitoring database logs for unusual query patterns can help detect exploitation attempts early. Organizations should also prepare incident response plans tailored to data breaches involving training systems. Finally, consider migrating to updated or alternative training management solutions with robust security practices if patches are delayed.
