CVE-2025-40666 is a high-severity SQL injection vulnerability identified in version 11 of TCMAN's GIM product. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), specifically through the 'ArbolID' parameter in the endpoint /GIMWeb/PC/frmPreventivosList.aspx. This is a time-based blind SQL injection, meaning that an attacker can infer data from the database by observing response delays caused by injected SQL commands that execute conditional time delays. Exploiting this vulnerability allows an attacker to perform unauthorized actions on the backend database, including retrieving, creating, updating, and deleting data. The CVSS 4.0 score is 8.7 (high), reflecting 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 potential for exploitation is high given the ease of attack and critical impact. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability affects a widely used enterprise asset management system, which may contain sensitive operational and maintenance data critical to organizational functions.

For European organizations using TCMAN GIM v11, this vulnerability poses a substantial risk. Successful exploitation could lead to unauthorized data disclosure, modification, or deletion, impacting operational continuity and data integrity. This could disrupt maintenance schedules, asset tracking, and other critical infrastructure management processes. Confidential information stored within the database, including potentially sensitive operational details or personally identifiable information, could be exposed or manipulated. The high impact on availability could result in denial of service conditions, further affecting business operations. Given the network-exploitable nature and no requirement for user interaction, attackers could remotely compromise systems without insider access. This risk is particularly acute for industries relying heavily on asset management systems, such as manufacturing, utilities, transportation, and public infrastructure sectors prevalent in Europe. The absence of known exploits currently provides a window for proactive defense, but the high severity score indicates that exploitation could have severe consequences.

European organizations should immediately assess their exposure to TCMAN GIM v11 and prioritize remediation. Specific mitigation steps include: 1) Conduct a thorough inventory to identify all instances of TCMAN GIM v11 in use. 2) Apply any available vendor patches or updates as soon as they are released; if no patches are available, engage with the vendor for timelines and interim fixes. 3) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ArbolID' parameter, including time-based blind injection attempts. 4) Employ strict input validation and parameterized queries in custom integrations or scripts interfacing with GIM, if applicable. 5) Monitor network traffic and application logs for anomalous delays or suspicious queries indicative of time-based SQL injection attempts. 6) Restrict database user privileges associated with the GIM application to the minimum necessary to limit potential damage. 7) Segment the network to isolate critical asset management systems from broader enterprise networks and external access where possible. 8) Conduct penetration testing focused on SQL injection vectors to validate the effectiveness of mitigations. 9) Train security teams and administrators on recognizing and responding to SQL injection attacks specific to this product. These targeted actions go beyond generic advice by focusing on the known vulnerable parameter, the nature of the injection, and the operational context of TCMAN GIM deployments.
