EUVD-2025-37924

Comprehensive Technical Analysis of EUVD-2025-37924

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-37924 affects Quipux versions 4.0.1 through e1774ac, allowing authenticated users to conduct SQL injection attacks via multiple endpoints. This vulnerability is critical due to the potential for unauthorized access to sensitive data, data manipulation, and system compromise.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 9.9 indicates a critical vulnerability. The attack vector (AV:N) is network-based, requiring low complexity (AC:L) and low privileges (PR:L). The user interaction (UI:N) is not required, and the scope (S:C) is changed, leading to high confidentiality, integrity, and availability impacts (C:H/I:H/A:H).
