CVE-2025-8135 is a SQL Injection vulnerability identified in the itsourcecode Insurance Management System version 1.0. The vulnerability is located in the /updateAgent.php file, specifically in the handling of the 'agent_id' parameter. An attacker can manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access or modification of the backend database. The vulnerability is remotely exploitable without requiring user interaction or prior authentication, making it a significant risk. The CVSS 4.0 base score is 5.3 (medium severity), reflecting that while the attack vector is network-based and requires no user interaction, it does require low privileges and the impact on confidentiality, integrity, and availability is limited to low levels. However, SQL injection vulnerabilities inherently carry risks of data leakage, unauthorized data modification, or even full database compromise depending on the backend database and application logic. The vulnerability affects only version 1.0 of the product, and no patches or fixes have been publicly disclosed yet. No known exploits are currently reported in the wild, but public disclosure increases the risk of exploitation attempts.

For European organizations using the itsourcecode Insurance Management System 1.0, this vulnerability poses a risk of unauthorized data access or manipulation within their insurance management databases. Given the sensitive nature of insurance data, including personal customer information and financial records, exploitation could lead to data breaches violating GDPR and other privacy regulations, resulting in legal penalties and reputational damage. The ability to remotely exploit the vulnerability without authentication increases the threat level, especially for organizations with internet-facing instances of the affected system. Although the CVSS score is medium, the potential impact on data confidentiality and integrity could be significant if exploited, particularly for insurers handling large volumes of personal data. Additionally, disruption or corruption of insurance agent data could impact business operations and customer service continuity.

Organizations should immediately audit their use of the itsourcecode Insurance Management System and identify any instances of version 1.0 in their environment. Since no official patch is currently available, mitigation should focus on implementing Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'agent_id' parameter in /updateAgent.php. Input validation and parameterized queries should be enforced if organizations have the capability to modify the application code. Network segmentation and restricting access to the affected system to trusted internal networks can reduce exposure. Monitoring logs for suspicious database queries or unusual activity related to the updateAgent.php endpoint is critical for early detection. Organizations should also engage with the vendor for updates or patches and plan for an upgrade to a fixed version once available. Finally, conducting penetration testing focused on SQL injection vectors can help identify residual risks.
