Comprehensive Technical Analysis of EUVD-2025-21717

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in WeGIA, an open-source web manager, is a SQL Injection vulnerability in the /controle/control.php endpoint, specifically affecting the cargo parameter. This vulnerability allows attackers to execute arbitrary SQL commands, which can compromise the confidentiality, integrity, and availability of the database.

Severity Evaluation:

• Base Score: 9.4
• Base Score Version: 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 of 9.4 indicates a critical vulnerability. The CVSS vector breakdown shows that the attack vector is network-based (AV:N), the attack complexity is low (AC:L), and no user interaction is required (UI:N). The vulnerability has high impacts on confidentiality, integrity, and availability (VC:H, VI:H, VA:H), and the scope change is high (SC:H), affecting the security impact (SI:H) and availability impact (SA:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attack: The vulnerability can be exploited remotely over the network.
• Low Complexity: The attack does not require sophisticated techniques or tools.
• No User Interaction: The attack can be executed without any interaction from the user.

Exploitation Methods:

• SQL Injection: Attackers can inject malicious SQL code into the cargo parameter of the /controle/control.php endpoint.
• Arbitrary SQL Execution: This can lead to unauthorized access to the database, data exfiltration, data manipulation, and potential denial of service.

3. Affected Systems and Software Versions

Affected Software:

• WeGIA: Versions prior to 3.4.5

Vendor and Product Information:
