EUVD-2025-208457

Comprehensive Technical Analysis of EUVD-2025-208457

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in Hitachi Vantara Pentaho Data Integration & Analytics versions before 10.2.0.6 allows users to insert arbitrary Groovy scripts in new PRPT reports. This lack of restriction can lead to Remote Code Execution (RCE).

Severity Evaluation:

• Base Score: 9.1 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 9.1 indicates a critical vulnerability. The vector string breaks down as follows:

• AV:N (Network Vector): The vulnerability is exploitable over the network.
• AC:L (Low Complexity): The attack requires low skill or resources.
• PR:H (High Privileges Required): The attacker needs high-level privileges to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required for the attack to succeed.
• S:C (Changed Scope): The vulnerability can affect resources beyond the security scope managed by the security authority.
• C:H/I:H/A:H (High Confidentiality, Integrity, and Availability Impact): Successful exploitation can lead to high impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the network vector (AV:N), attackers can exploit this vulnerability remotely.
• Privileged User Accounts: The attacker needs high-level privileges (PR:H), indicating that the attacker must have access to a privileged user account.

Exploitation Methods:

• Arbitrary Script Insertion: An attacker with the necessary privileges can insert malicious Groovy scripts into PRPT reports.
• Remote Code Execution: The inserted scripts can be executed remotely, leading to RCE.

3. Affected Systems and Software Versions

Affected Software:

• Hitachi Vantara Pentaho Data Integration & Analytics versions before 10.2.0.6
• Specifically, versions 9.3.x and 8.3.x are impacted.

Affected Systems:

• Systems running the affected versions of Pentaho Data Integration & Analytics.
• Environments where users have the capability to publish new PRPT reports.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade Software: Upgrade to version 10.2.0.6 or later to mitigate the vulnerability.
• Restrict User Privileges: Ensure that only trusted users have the privileges to publish PRPT reports.
• Monitor and Audit: Implement monitoring and auditing of user activities, especially those related to report publishing.

Long-Term Strategies:

• Regular Patch Management: Establish a regular patch management process to ensure timely updates.
• Security Training: Provide security training to users and administrators to recognize and mitigate potential threats.
• Network Segmentation: Implement network segmentation to limit the impact of potential RCE attacks.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• Organizations must comply with regulations such as GDPR, which mandates the protection of personal data.
• Failure to address this vulnerability could result in data breaches, leading to regulatory penalties and loss of trust.

Industry Impact:

• Data Integration and Analytics: The vulnerability affects a critical tool used in data integration and analytics, impacting various industries including finance, healthcare, and manufacturing.
• Supply Chain: Organizations relying on Pentaho for supply chain analytics must ensure their systems are secure to prevent disruptions.

6. Technical Details for Security Professionals

Detection:

• Log Analysis: Monitor logs for unusual script execution or unauthorized access attempts.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious activities related to PRPT report publishing.

Response:

• Incident Response Plan: Develop and implement an incident response plan specific to RCE vulnerabilities.
• Forensic Analysis: Conduct forensic analysis to identify the source and extent of the breach if an exploitation is detected.

Prevention:

• Code Review: Conduct thorough code reviews to ensure that Groovy scripts are properly restricted.
• Access Control: Implement strict access control policies to limit the number of users with high privileges.
