CVE-2025-9122 is an information disclosure vulnerability classified under CWE-209, affecting Hitachi Vantara Pentaho Data Integration and Analytics Community Dashboard Framework versions prior to 10.2.0.4, including 9.3.0.x and 8.3.x. The vulnerability arises because the GetCdfResource servlet improperly handles error conditions by displaying the full server stack trace to the client. This stack trace can contain sensitive information such as file paths, configuration details, software versions, and internal logic flows. Attackers can exploit this flaw remotely over the network without requiring authentication or user interaction, making it easier to gather intelligence on the target system. Although the vulnerability does not allow direct code execution, privilege escalation, or denial of service, the exposure of internal details can facilitate more sophisticated attacks by revealing potential weaknesses or misconfigurations. The CVSS v3.1 base score is 5.3 (medium), reflecting the moderate impact on confidentiality and the ease of exploitation. No patches or exploits are currently publicly available, but organizations are advised to upgrade to version 10.2.0.4 or later once released or implement custom error handling to suppress detailed error messages. This vulnerability highlights the importance of secure error management in web applications, especially in data analytics platforms that handle sensitive business intelligence data.

For European organizations, the primary impact of CVE-2025-9122 is the inadvertent disclosure of sensitive internal information through detailed error messages. This can aid attackers in reconnaissance activities, enabling them to map the system architecture, identify software versions, and discover potential vulnerabilities or misconfigurations. Such intelligence can be leveraged to craft targeted attacks, including injection attacks, privilege escalation, or lateral movement within networks. While the vulnerability itself does not directly compromise data integrity or availability, the information leakage increases the overall attack surface and risk profile. Organizations relying heavily on Pentaho for critical data integration and analytics may face increased exposure, especially if combined with other vulnerabilities. The lack of authentication or user interaction requirements means attackers can probe systems remotely with minimal barriers. This is particularly concerning for sectors with sensitive data such as finance, healthcare, and government agencies within Europe. Failure to mitigate this vulnerability could lead to more severe breaches facilitated by the initial information disclosure.

To mitigate CVE-2025-9122, European organizations should prioritize upgrading Hitachi Vantara Pentaho Data Integration and Analytics to version 10.2.0.4 or later, where the vulnerability is addressed. In the absence of an immediate patch, organizations can implement custom error handling mechanisms to suppress detailed stack traces from being displayed to end users. This can be achieved by configuring the web server or application framework to return generic error messages without revealing internal details. Additionally, organizations should conduct thorough audits of their Pentaho deployments to identify exposed endpoints such as the GetCdfResource servlet and restrict access via network segmentation or firewall rules where feasible. Monitoring and logging access to these endpoints can help detect suspicious probing activity. Security teams should also review application and server logs for any unusual error message disclosures and ensure that development and testing environments do not inadvertently expose verbose error information. Finally, integrating this vulnerability awareness into incident response and threat hunting workflows will help prepare for potential exploitation attempts.
