AI-suggested
- Immediate application of vendor patches once available is the most effective mitigation. Monitor Grupo Castilla advisories for updates.
- Until patches are released, implement strict input validation on the 'sEstadoUsr' parameter to reject or sanitize any SQL control characters or suspicious payloads.
- Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /epsilonnetws/WSAvisos.asmx endpoint.
- Restrict network access to the vulnerable endpoint by limiting exposure to trusted internal networks or VPNs only.
- Conduct thorough security audits and penetration testing focused on web services and API endpoints to identify similar injection flaws.
- Monitor logs for unusual POST requests or database errors indicative of exploitation attempts.
- Educate development and security teams on secure coding practices to prevent SQL injection vulnerabilities in future releases.
- Consider database-level protections such as least privilege for application accounts and query parameterization to reduce impact if exploitation occurs.
Description
CVE-2025-41028 is a critical SQL Injection vulnerability in Grupo Castilla's Epsilon RH version 3.03.36.010. It allows unauthenticated attackers to manipulate the database by sending crafted POST requests to the /epsilonnetws/WSAvisos.asmx endpoint using the 'sEstadoUsr' parameter. Exploitation can lead to full database compromise including data retrieval, creation, modification, and deletion without any user interaction or privileges. The vulnerability has a CVSS 4.0 score of 9.3, reflecting its high impact and ease of exploitation.
