EUVD-2025-5097

Comprehensive Technical Analysis of EUVD-2025-5097

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in EUVD-2025-5097 is a Path Traversal issue in the examples.php endpoint of the WeGIA application. This vulnerability allows an attacker to gain unauthorized access to sensitive information stored in config.php, which contains critical details such as database credentials. The severity of this vulnerability is rated with a CVSS Base Score of 10.0, indicating a critical risk. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Changed (C) - The vulnerability affects resources beyond the security scope managed by the security authority.
• Confidentiality (C): High (H) - There is a high impact on the confidentiality of the data.
• Integrity (I): High (H) - There is a high impact on the integrity of the data.
• Availability (A): High (H) - There is a high impact on the availability of the system.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through the examples.php endpoint. An attacker could manipulate the input parameters to traverse directories and access the config.php file. This file typically contains sensitive information such as database credentials, which could be used to gain unauthorized access to the database.

Exploitation Methods:

• Directory Traversal: By manipulating the input parameters, an attacker can navigate through the directory structure to access config.php.
• Information Disclosure: Once the attacker gains access to config.php, they can extract sensitive information such as database credentials.
• Database Access: Using the extracted credentials, the attacker can gain direct access to the database, leading to potential data breaches, data manipulation, or service disruption.

3. Affected Systems and Software Versions

The vulnerability affects all versions of WeGIA prior to version 3.2.14. Specifically:

• WeGIA versions < 3.2.14

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade to Version 3.2.14: All users are strongly advised to upgrade to WeGIA version 3.2.14 or later, where the vulnerability has been addressed.

Additional Mitigation Steps:

• Input Validation: Implement strict input validation and sanitization to prevent directory traversal attacks.
• Access Controls: Restrict access to sensitive files such as config.php using proper file permissions and access controls.
• Monitoring and Logging: Enable comprehensive logging and monitoring to detect and respond to any suspicious activities.
• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential security risks.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, an open-source Web Manager primarily used by Portuguese language institutions, poses a significant risk to the European cybersecurity landscape. Given the critical nature of the vulnerability and its potential to expose sensitive information, it could lead to data breaches, unauthorized access, and potential service disruptions. This underscores the importance of timely patching and regular security assessments for open-source software used in critical sectors.

6. Technical Details for Security Professionals
