Deeper analysis
CVE-2025-40715 is a SQL injection vulnerability (CWE-89) affecting Quiter Gateway by Quiter in versions prior to 4.7.0. The flaw resides in the "campo mensaje" parameter of the /QISClient/api/v1/sucesospaginas endpoint, enabling improper handling of user-supplied input that leads to injectable SQL queries. With a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), it represents critical risk due to its high impact on confidentiality, integrity, and availability.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows arbitrary database operations, including retrieving sensitive data, creating new databases or records, updating existing ones, and deleting databases or data, potentially leading to complete compromise of the underlying database.
The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-quiterweb-autoweb-quiter details this among multiple vulnerabilities in Quiter products, recommending upgrade to version 4.7.0 or later to mitigate the issue.
