Technical Analysis

CVE-2025-26147 is an authenticated remote code execution (RCE) vulnerability identified in the Denodo Scheduler component. Denodo Scheduler is part of the Denodo Platform, a data virtualization solution widely used for integrating and managing data from multiple sources. This vulnerability requires an attacker to have valid authentication credentials to the Denodo Scheduler, which then allows them to execute arbitrary code remotely on the underlying system. Although specific technical details such as the exact attack vector, exploited functions, or vulnerable versions are not provided, the nature of an authenticated RCE implies that an attacker who gains access to the scheduler interface can execute commands or deploy malicious payloads, potentially compromising the host system. The vulnerability was publicly disclosed on May 21, 2025, through a Reddit NetSec post with limited discussion and no known exploits in the wild at the time of reporting. No official patches or version-specific information have been released yet, indicating that organizations using Denodo Scheduler should be vigilant and monitor for vendor advisories. The medium severity rating suggests that while the vulnerability is serious, exploitation requires authentication, which limits the attack surface compared to unauthenticated RCEs. However, given the critical role of Denodo Scheduler in data workflows, successful exploitation could lead to significant operational disruption and data compromise.

Potential Impact

For European organizations, the impact of this vulnerability could be substantial, especially for enterprises relying on Denodo Platform for data integration and analytics. An attacker exploiting this authenticated RCE could execute arbitrary code, leading to unauthorized access to sensitive data, disruption of scheduled data processing tasks, and potential lateral movement within the network. This could compromise confidentiality, integrity, and availability of critical business data and services. Organizations in sectors such as finance, healthcare, manufacturing, and government, which often use data virtualization for regulatory reporting and operational intelligence, may face compliance risks and operational downtime. Moreover, the requirement for authentication means insider threats or compromised credentials pose a significant risk vector. The lack of known exploits currently provides a window for proactive defense, but the medium severity rating should not lead to complacency given the potential for escalation and data breaches.

Mitigation Recommendations

To mitigate this threat effectively, European organizations should: 1) Immediately review and tighten access controls to the Denodo Scheduler, ensuring that only authorized personnel have scheduler access and that strong authentication mechanisms (e.g., multi-factor authentication) are enforced. 2) Monitor authentication logs and scheduler activity for unusual or unauthorized access attempts. 3) Implement network segmentation to isolate the Denodo Scheduler from broader enterprise networks, limiting the potential impact of a compromised scheduler. 4) Engage with Denodo support and subscribe to their security advisories to obtain patches or workarounds as soon as they become available. 5) Conduct internal security assessments and penetration tests focusing on the Denodo Scheduler environment to identify and remediate potential weaknesses. 6) Educate administrators and users about credential security to reduce the risk of credential compromise. 7) Consider deploying application-layer firewalls or runtime application self-protection (RASP) solutions to detect and block suspicious command execution attempts within the scheduler interface.
