Overview
CVE-2025-63291 details an Insecure Direct Object Reference (IDOR) vulnerability found in Alteryx Server versions 2022.1.1.42654 and 2024.1. This flaw allows an attacker with authenticated access to the Alteryx Server API to potentially retrieve sensitive data belonging to other users, including administrative and private studio API keys, by manipulating MongoDB object IDs in API requests.
Technical Details
The Alteryx server utilizes MongoDB object IDs as unique identifiers when processing API requests. Due to a lack of proper authorization checks, the server fails to verify if the authenticated user has the necessary permissions to access the data associated with a specific MongoDB object ID. An attacker can exploit this by crafting API requests with manipulated MongoDB object IDs, effectively bypassing intended access controls and retrieving records for which they are not authorized. The retrieved records can include highly sensitive information such as administrative API keys and private studio API keys.
CVSS Analysis
At the time of writing, a CVSS score has not been assigned to CVE-2025-63291. However, given the potential for unauthorized access to administrative API keys and the associated risk of complete server compromise, the vulnerability is likely to be assessed as High to Critical severity upon official CVSS scoring.
Possible Impact
The exploitation of CVE-2025-63291 can have severe consequences:
- Data Breach: Unauthorized access to sensitive data belonging to other users.
- Account Takeover: Compromised administrative API keys can be used to gain full control over the Alteryx server.
- Lateral Movement: Access to private studio API keys might enable attackers to gain access to associated user accounts and resources.
- Service Disruption: Modification or deletion of data due to unauthorized access.
- Reputation Damage: Loss of trust and confidence in the organization due to a security breach.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-63291, it is crucial to take the following steps:
- Upgrade Alteryx Server: Apply the latest security patches and upgrades provided by Alteryx as soon as they become available. Check the Alteryx support portal for updates.
- Implement Proper Authorization Checks: Ensure that all API endpoints that utilize MongoDB object IDs implement robust authorization checks to verify that the authenticated user has the necessary permissions to access the requested data.
- Principle of Least Privilege: Limit user permissions to the minimum required to perform their job functions.
- Monitor API Access: Implement monitoring and logging of API access attempts to detect and respond to suspicious activity.
