CVE-2025-41019 is a critical SQL injection vulnerability identified in Sergestec's SISTICK software, specifically version 7.2. The vulnerability stems from improper neutralization of special characters in the 'id' parameter within the '/index.php?view=ticket_detail' endpoint. This allows attackers to inject malicious SQL commands directly into the backend database queries without requiring authentication or user interaction. Exploitation can lead to unauthorized retrieval, creation, modification, or deletion of database records, severely compromising data confidentiality, integrity, and availability. The CVSS 4.0 score of 9.3 reflects the vulnerability's high severity, with network attack vector, low complexity, no privileges required, and no user interaction needed. The vulnerability affects the core data handling of SISTICK, a product used for ticket management, which may contain sensitive operational or customer data. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers aiming to gain persistent access or disrupt services. The lack of available patches at the time of publication necessitates immediate mitigation efforts. The vulnerability was reserved in April 2025 and published in October 2025 by INCIBE, indicating coordinated disclosure. Given the critical nature of SQL injection flaws, organizations must assess their exposure and implement robust input validation, use prepared statements or parameterized queries, and enforce least privilege on database accounts to mitigate potential exploitation.

For European organizations, the impact of CVE-2025-41019 can be severe. Exploitation could lead to unauthorized access to sensitive data, including personal information, operational details, or intellectual property, violating GDPR and other data protection regulations. Data integrity could be compromised by unauthorized modifications or deletions, potentially disrupting business operations or causing financial losses. Availability of services relying on SISTICK could be affected if attackers delete or corrupt critical database records. The vulnerability's ease of exploitation without authentication increases the risk of widespread attacks, especially in sectors such as government, healthcare, finance, and critical infrastructure where SISTICK might be deployed. Additionally, successful exploitation could serve as a foothold for further network intrusion or lateral movement. The reputational damage and regulatory penalties resulting from a breach could be substantial. Organizations in Europe must consider the legal and operational consequences of this vulnerability and prioritize remediation to maintain trust and compliance.

1. Immediate mitigation should focus on implementing strict input validation and sanitization on the 'id' parameter to prevent malicious SQL code injection. 2. Refactor the application code to use parameterized queries or prepared statements instead of dynamic SQL concatenation. 3. Restrict database user permissions to the minimum necessary, avoiding use of highly privileged accounts for application database connections. 4. Monitor application logs and database activity for unusual queries or access patterns indicative of exploitation attempts. 5. Deploy web application firewalls (WAFs) with rules specifically targeting SQL injection patterns on the affected endpoint. 6. Engage with Sergestec for official patches or updates and apply them as soon as they become available. 7. Conduct security audits and penetration testing focused on input validation and injection flaws. 8. Educate developers and administrators on secure coding practices to prevent similar vulnerabilities. 9. Isolate the SISTICK application environment to limit potential lateral movement if compromised. 10. Prepare incident response plans to quickly contain and remediate any detected exploitation.
