CVE-2025-40698 is a high-severity SQL injection vulnerability identified in Prevengos version 2.44, a product developed by Nedatec Consulting. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), specifically in the web service endpoint /servicios/autorizaciones.asmx/mfsRecuperarListado. An attacker can exploit this flaw by sending crafted POST requests with manipulated parameters: “mpsCentroin”, “mpsEmpresa”, “mpsProyecto”, and “mpsContrata”. Due to insufficient input validation or sanitization, these parameters allow injection of malicious SQL code. This enables an attacker to perform unauthorized actions on the backend database, including retrieving sensitive data, creating, updating, or deleting database records. The vulnerability requires no user interaction and no authentication, making it remotely exploitable over the network (AV:N), with low attack complexity (AC:L). The CVSS 4.0 score of 8.7 reflects the high impact on confidentiality, integrity, and availability, as the attacker can fully manipulate database contents and access sensitive information. Although no known exploits are currently reported in the wild, the vulnerability’s characteristics make it a critical risk if weaponized. The lack of available patches at the time of publication increases the urgency for mitigation. Prevengos is a specialized software product, and the vulnerability is specific to version 2.44, but the exact market penetration and deployment scale are not detailed in the provided data.

For European organizations using Prevengos v2.44, this vulnerability poses a significant threat to data security and operational integrity. Successful exploitation could lead to unauthorized disclosure of sensitive corporate or personal data, manipulation or destruction of critical records, and potential disruption of business processes relying on the affected database. This could result in regulatory non-compliance, especially under GDPR, financial losses, reputational damage, and operational downtime. The ability to modify database contents could also facilitate further attacks, such as privilege escalation or persistent backdoors. Given the high CVSS score and the lack of authentication requirements, attackers can remotely exploit this vulnerability without insider access, increasing the risk profile for organizations in sectors where Prevengos is deployed, such as consulting, project management, or service authorization workflows. The absence of known exploits in the wild currently provides a window for proactive defense but should not reduce urgency for remediation.

1. Immediate mitigation should focus on restricting access to the vulnerable endpoint /servicios/autorizaciones.asmx/mfsRecuperarListado by implementing network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2. Employ Web Application Firewalls (WAFs) configured with custom rules to detect and block SQL injection patterns targeting the specified parameters. 3. Conduct thorough input validation and sanitization on all user-supplied data, especially the parameters “mpsCentroin”, “mpsEmpresa”, “mpsProyecto”, and “mpsContrata”, ensuring that only expected data types and formats are accepted. 4. If possible, apply parameterized queries or stored procedures in the backend code to prevent injection. 5. Monitor logs for unusual database queries or repeated failed attempts to access the endpoint. 6. Engage with Nedatec Consulting to obtain or request patches or updates addressing this vulnerability. 7. Plan for an urgent update cycle once a patch is available, including testing in a staging environment to confirm the fix. 8. Educate development and security teams about secure coding practices to prevent similar vulnerabilities in future releases.
