CVE-2025-15097 is an improper authentication vulnerability identified in Alteryx Server, specifically impacting an unknown functionality within the /gallery/api/status/ endpoint. This flaw allows an unauthenticated remote attacker to manipulate requests to bypass authentication controls, potentially gaining unauthorized access to server resources. The vulnerability affects a wide range of Alteryx Server versions from 2020.2.3.27789 up to various 2024.2.1.x builds, with fixed versions released starting from 2023.1.1.13.486 and later. The CVSS 4.0 base score is 6.9, reflecting a medium severity level, with attack vector being network-based, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, the public availability of exploit code increases the risk of future attacks. The vulnerability could allow attackers to access sensitive data, modify workflows, or disrupt analytics operations, undermining trust in the platform. The lack of scope change indicates the impact is limited to the vulnerable component without affecting other system components directly. The vulnerability’s root cause is improper authentication logic in the API endpoint, which should be addressed by upgrading to the patched versions provided by Alteryx.

For European organizations, the improper authentication vulnerability in Alteryx Server poses a significant risk to data confidentiality, integrity, and availability. Alteryx Server is widely used for data analytics, business intelligence, and workflow automation, often processing sensitive or regulated data. Unauthorized access could lead to data leakage, manipulation of analytics workflows, or disruption of critical business processes. This could result in regulatory non-compliance, financial losses, reputational damage, and operational downtime. Organizations in sectors such as finance, healthcare, manufacturing, and government are particularly vulnerable due to their reliance on data-driven decision-making and strict data protection regulations like GDPR. The remote exploitability without authentication or user interaction increases the threat level, especially for internet-facing deployments. Although no known exploits are currently active, the public disclosure of exploit details necessitates immediate action to prevent potential attacks. The medium severity rating reflects a balanced risk but should not lead to complacency given the criticality of data handled by Alteryx Server in European enterprises.

To mitigate CVE-2025-15097, European organizations should: 1) Immediately upgrade Alteryx Server to one of the patched versions: 2023.1.1.13.486, 2023.2.1.10.293, 2024.1.1.9.236, 2024.2.1.6.125, or 2025.1.1.1.31, as appropriate. 2) Restrict network access to the Alteryx Server, especially the /gallery/api/status/ endpoint, by implementing firewall rules or network segmentation to limit exposure to trusted internal networks. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious API requests targeting the vulnerable endpoint. 4) Monitor server logs for unusual access patterns or repeated unauthorized attempts to access the API endpoint. 5) Conduct regular vulnerability scans and penetration tests focusing on authentication mechanisms of critical applications. 6) Review and enforce strict access control policies and multi-factor authentication for administrative access to Alteryx Server. 7) Maintain an incident response plan to quickly address any suspected compromise related to this vulnerability. 8) Engage with Alteryx support and subscribe to security advisories to stay informed about future patches or related vulnerabilities.
