CVE-2025-40624 is a critical SQL injection vulnerability identified in TCMAN's GIM product, specifically version 11. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated attacker to inject malicious SQL statements through the 'User' and 'email' parameters of the 'updatePassword' endpoint. This flaw enables attackers to perform unauthorized actions on the backend database, including reading, modifying, and deleting all stored information. The vulnerability is remotely exploitable without any authentication or user interaction, making it highly dangerous. The CVSS 4.0 score of 9.3 reflects its critical severity, with attack vector being network-based, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Although no public exploits are currently known, the ease of exploitation and the critical impact make this a significant threat. The vulnerability affects all installations running GIM v11, which is a management product by TCMAN, presumably used in enterprise environments for identity or resource management. The lack of available patches at the time of publication increases the urgency for mitigation and risk management.

For European organizations using TCMAN GIM v11, this vulnerability poses a severe risk. Successful exploitation could lead to complete compromise of the database, resulting in unauthorized disclosure of sensitive information, data manipulation, or destruction. This could disrupt business operations, cause regulatory compliance violations (e.g., GDPR breaches due to data exposure), and damage organizational reputation. Given the unauthenticated remote exploitability, attackers can leverage this vulnerability to gain persistent access or pivot to other internal systems. Critical sectors such as finance, healthcare, government, and critical infrastructure that rely on TCMAN GIM for identity or resource management are particularly at risk. The potential for data loss or corruption could also impact service availability and continuity. Additionally, the breach of personal data could trigger legal and financial penalties under European data protection laws.

Immediate mitigation steps include: 1) Implement strict input validation and sanitization on the 'User' and 'email' parameters of the 'updatePassword' endpoint to prevent SQL injection. 2) Employ parameterized queries or prepared statements in the application code to separate SQL logic from data inputs. 3) Restrict database permissions for the application to the minimum necessary, preventing unauthorized data modification or deletion even if injection occurs. 4) Monitor network traffic and application logs for unusual or suspicious SQL queries targeting the vulnerable endpoint. 5) If possible, temporarily disable or restrict access to the 'updatePassword' endpoint until a vendor patch is available. 6) Engage with TCMAN for official patches or updates and apply them promptly once released. 7) Conduct a thorough security review and penetration testing of the GIM deployment to identify any other injection points or vulnerabilities. 8) Implement Web Application Firewalls (WAF) with rules to detect and block SQL injection attempts targeting this endpoint. These measures go beyond generic advice by focusing on specific parameters and endpoint, emphasizing least privilege, monitoring, and vendor coordination.
