Comprehensive Technical Analysis of EUVD-2025-3982

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2025-3982 describes a SQL Injection vulnerability in the WeGIA application, specifically in the deletar_permissao.php endpoint. This vulnerability allows an authorized attacker to execute arbitrary SQL queries, potentially leading to unauthorized access, modification, or deletion of sensitive information.

Severity Evaluation:

• Base Score: 9.4 (CVSS 4.0)
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

The high base score indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): Low (L)
• User Interaction (UI): None (N)
• Confidentiality (VC), Integrity (VI), and Availability (VA) Impact: High (H)
• Scope Change (SC): High (H)
• Secondary Impact (SI): High (H)
• Secondary Availability (SA): High (H)

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: The vulnerability can be exploited remotely over the network.
• Authenticated Users: The attacker needs to be authenticated, but with low privileges.

Exploitation Methods:
