Comprehensive Technical Analysis of EUVD-2025-23358

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-23358 pertains to a SQL injection flaw in Gandia Integra Total, a software product by TESI. This vulnerability affects versions ranging from 2.1.2217.3 to 4.4.2236.1. The CVSS (Common Vulnerability Scoring System) base score of 9.3 indicates a critical severity level. The CVSS vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it is relatively easy to exploit.
• AT:N (None): No special authentication is required.
• PR:N (None): No privileges are required.
• UI:N (None): No user interaction is required.
• VC:H (High): Confidentiality impact is high.
• VI:H (High): Integrity impact is high.
• VA:H (High): Availability impact is high.
• SC:N (None): Scope change is not applicable.
• SI:N (None): Scope impact is not applicable.
• SA:N (None): Scope availability is not applicable.

This high severity score underscores the critical nature of the vulnerability, which can lead to significant data breaches and system compromises.

2. Potential Attack Vectors and Exploitation Methods

The SQL injection vulnerability can be exploited through the idestudio parameter in the URL path /encuestas/integraweb_v4/integra/html/view/acceso.php. An attacker can inject malicious SQL queries into this parameter to manipulate the database. Potential attack vectors include:

• Data Exfiltration: Retrieving sensitive information from the database.
• Data Manipulation: Creating, updating, or deleting database records.
• Privilege Escalation: Gaining unauthorized access to other parts of the system.
• Denial of Service: Overloading the database with malicious queries to disrupt service.

3. Affected Systems and Software Versions

The vulnerability affects Gandia Integra Total versions from 2.1.2217.3 to 4.4.2236.1. Organizations using these versions are at risk and should prioritize patching or mitigating the issue.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Apply the latest patches and updates provided by TESI.
• Input Validation: Implement robust input validation and sanitization for all user inputs, especially the idestudio parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block malicious SQL injection attempts.
• Database Permissions: Restrict database permissions to the minimum necessary for application functionality.
• Regular Audits: Conduct regular security audits and vulnerability assessments.

5. Impact on European Cybersecurity Landscape

The vulnerability in Gandia Integra Total, a widely used software in Europe, poses a significant risk to the European cybersecurity landscape. Organizations relying on this software for data management and integration are particularly vulnerable. The potential for data breaches and system compromises could lead to financial losses, reputational damage, and legal consequences under GDPR (General Data Protection Regulation).

6. Technical Details for Security Professionals

Vulnerability Details:

• Affected Parameter: idestudio
• Affected URL: /encuestas/integraweb_v4/integra/html/view/acceso.php
• Exploitation Method: Injecting malicious SQL queries into the idestudio parameter.

Example Exploit:

idestudio=1'; DROP TABLE users; --

This example demonstrates a simple SQL injection attack that could delete a table named users.

Detection:

• Log Analysis: Monitor database logs for unusual SQL queries.
• Intrusion Detection Systems (IDS): Implement IDS to detect anomalous database activities.
• Code Review: Conduct a thorough code review to identify and fix SQL injection vulnerabilities.

Remediation:

• Code Fix: Ensure all SQL queries use parameterized statements.
• Database Security: Implement least privilege access controls for database users.
• Regular Updates: Keep the software and all dependencies up to date with the latest security patches.
