Comprehensive Technical Analysis of EUVD-2024-27668

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2024-27668 describes a SQL injection vulnerability in the CIGESv2 system, specifically through the /ajaxSubServicios.php endpoint in the idServicio parameter. This vulnerability allows a remote attacker to execute arbitrary SQL queries, potentially leading to unauthorized data retrieval, modification, or deletion.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high score underscores the potential for severe impact on confidentiality, integrity, and availability of the affected system.
