CVE-2025-6135 is a critical SQL Injection vulnerability identified in version 1.0 of the Projectworlds Life Insurance Management System, specifically within the /insertNominee.php file. The vulnerability arises due to improper sanitization or validation of user-supplied input parameters, namely client_id and nominee_id, which are directly used in SQL queries. An attacker can remotely manipulate these parameters to inject malicious SQL code, potentially altering the intended SQL commands executed by the backend database. This can lead to unauthorized data access, data modification, or even deletion, compromising the confidentiality, integrity, and availability of the insurance management system's data. The vulnerability requires no user interaction and can be exploited remotely without authentication, increasing its risk profile. Although the CVSS 4.0 score is 5.3 (medium severity), the nature of SQL injection vulnerabilities often allows attackers to escalate privileges or pivot within the network, which can have severe consequences. The exploit code has been publicly disclosed, increasing the likelihood of exploitation attempts. No patches or mitigations have been officially released by the vendor at the time of publication, and no known exploits are currently observed in the wild. The vulnerability affects only version 1.0 of the product, which is used to manage sensitive life insurance data, including client and nominee information, making it a high-value target for attackers aiming to steal personal data or disrupt insurance operations.

For European organizations using Projectworlds Life Insurance Management System 1.0, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized disclosure of sensitive personal and financial data of policyholders and nominees, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. Data integrity could be compromised, allowing attackers to alter insurance records, which may disrupt claims processing and lead to financial losses or legal liabilities. Availability impacts could arise if attackers execute destructive SQL commands, causing service outages or data loss. Given the critical nature of insurance services, such disruptions could affect customer trust and operational continuity. The remote, unauthenticated nature of the exploit increases the risk of widespread attacks, especially if the system is accessible from the internet or poorly segmented internal networks. European insurers are often targeted by cybercriminals due to the value of personal data and financial transactions, making this vulnerability particularly concerning.

1. Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block malicious SQL injection attempts targeting the client_id and nominee_id parameters in /insertNominee.php. 2. Conduct a thorough code review and apply proper input validation and parameterized queries (prepared statements) to eliminate SQL injection vectors in the affected code. 3. Restrict network access to the Life Insurance Management System, ensuring it is not directly exposed to the internet and is accessible only through secure VPNs or internal networks. 4. Monitor logs for unusual database query patterns or repeated failed attempts to manipulate client_id or nominee_id parameters. 5. Engage with the vendor to obtain patches or updates; if unavailable, consider temporary compensating controls such as input sanitization proxies. 6. Perform a comprehensive security audit of the entire application to identify and remediate any other injection or input validation flaws. 7. Educate development teams on secure coding practices, emphasizing the use of parameterized queries and input validation. 8. Prepare incident response plans specifically for data breaches involving personal insurance data, including notification procedures compliant with GDPR.
