CVE-2025-10610 identifies a critical SQL Injection vulnerability classified under CWE-89 in the Winsure software developed by SFS Consulting Information Processing Industry and Foreign Trade Inc. This vulnerability arises from improper neutralization of special characters in SQL commands, enabling attackers to inject malicious SQL queries. Specifically, it enables Blind SQL Injection, where attackers can infer database information by observing application responses without direct data disclosure. The flaw affects all versions of Winsure up to the version dated 21.08.2025. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, significantly increasing its risk profile. Successful exploitation can lead to unauthorized data disclosure, data manipulation, and potentially full system compromise, impacting confidentiality, integrity, and availability. The CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) underscores the critical severity, indicating low attack complexity, no privileges required, and no user interaction needed. Although no public exploits are reported yet, the vulnerability's nature and severity suggest that it could be targeted by threat actors soon. The lack of available patches at the time of reporting necessitates immediate attention to alternative mitigations. This vulnerability is particularly concerning for organizations relying on Winsure for insurance and financial processing, as attackers could leverage this flaw to access sensitive customer and business data or disrupt operations.

For European organizations, the impact of CVE-2025-10610 is substantial. Winsure is a software product used in insurance and financial sectors, which handle sensitive personal and financial data protected under strict regulations such as GDPR. Exploitation could lead to large-scale data breaches exposing personal identifiable information (PII), financial records, and confidential business information, resulting in regulatory penalties, reputational damage, and financial losses. The ability to alter or delete data threatens business integrity and operational continuity, potentially disrupting critical insurance and trade processing functions. Given the remote, unauthenticated nature of the attack, threat actors could exploit this vulnerability at scale, targeting multiple organizations across Europe. This is especially critical for organizations with internet-facing Winsure deployments or insufficient network segmentation. The vulnerability also increases the risk of ransomware or other secondary attacks if attackers gain persistent access. Overall, the threat poses a high risk to European enterprises in regulated industries, necessitating urgent risk management and mitigation efforts.

1. Immediate Actions: Implement strict network-level access controls to restrict external access to Winsure application interfaces, ideally limiting access to trusted internal networks or VPNs. 2. Input Validation: Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting Winsure endpoints. 3. Monitoring and Detection: Enable detailed logging and monitoring of database queries and application logs to identify anomalous or suspicious SQL activity indicative of injection attempts. 4. Segmentation: Isolate Winsure servers from other critical infrastructure to contain potential breaches. 5. Vendor Engagement: Maintain close communication with SFS Consulting for timely release of patches or official mitigations and apply updates immediately once available. 6. Code Review: For organizations with access to the source or customization capabilities, conduct thorough code audits focusing on SQL query construction and parameter handling to implement parameterized queries or prepared statements. 7. Incident Response Preparedness: Update incident response plans to include scenarios involving SQL injection exploitation and data breach containment. 8. User Awareness: Educate IT and security teams about the vulnerability specifics and the importance of rapid detection and response. These steps go beyond generic advice by focusing on network controls, monitoring, and vendor coordination tailored to the specific risks posed by this vulnerability.
