CVE-2025-40665 is a high-severity SQL injection vulnerability affecting version 11 of TCMAN's GIM product. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), specifically through the 'ArbolID' parameter in the /GIMWeb/PC/frmCorrectivosList.aspx endpoint. This is a time-based blind SQL injection, meaning attackers can infer data by measuring response times, even though direct error messages or data may not be returned. Exploiting this flaw allows an attacker to perform unauthorized actions on the backend database, including retrieval, creation, updating, and deletion of data. The CVSS 4.0 score of 8.7 reflects a high severity, with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H). The vulnerability does not require user interaction and can be exploited remotely, making it a significant risk. Although no known exploits are currently reported in the wild, the nature of the vulnerability and its ease of exploitation suggest that it could be targeted by attackers soon. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability is assigned and published by INCIBE, indicating recognition by a European cybersecurity authority.

For European organizations using TCMAN GIM v11, this vulnerability poses a critical risk to the confidentiality, integrity, and availability of their data. Given that GIM is likely used for management or operational purposes, unauthorized database access could lead to data breaches, manipulation of critical operational data, or disruption of services. This could result in regulatory non-compliance, especially under GDPR, financial losses, reputational damage, and operational downtime. The ability to create, update, or delete data means attackers could implant false information or erase critical records, severely impacting business continuity. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, particularly in sectors where TCMAN GIM is deployed for infrastructure or asset management. European organizations with interconnected systems may also face lateral movement risks if attackers leverage this vulnerability as an initial foothold.

1. Immediate mitigation should include restricting access to the vulnerable endpoint (/GIMWeb/PC/frmCorrectivosList.aspx) through network segmentation and firewall rules, limiting exposure to trusted IPs only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'ArbolID' parameter. 3. Conduct thorough input validation and sanitization on all parameters, especially 'ArbolID', to ensure special characters are properly neutralized before database queries are executed. 4. Monitor logs for unusual time delays or anomalous query patterns indicative of time-based blind SQL injection attempts. 5. Engage with TCMAN for official patches or updates; if unavailable, consider temporary workarounds such as disabling the vulnerable functionality if feasible. 6. Perform a comprehensive security assessment of all systems integrating with GIM to identify potential lateral movement paths. 7. Educate internal security teams about this vulnerability to enhance detection and response capabilities. 8. Plan for incident response readiness in case exploitation attempts are detected.
