CVE-2025-63291
📋 TL;DR
This CVE describes an Insecure Direct Object Reference (IDOR) vulnerability in Alteryx Server where authenticated users can access other users' data by manipulating MongoDB object IDs in API requests. The vulnerability allows unauthorized access to sensitive information including administrative and private API keys. Affected systems are Alteryx Server versions 2022.1.1.42654 and 2024.1.
💻 Affected Systems
- Alteryx Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative API keys, leading to complete system compromise, data exfiltration, and privilege escalation across the Alteryx environment.
Likely Case
Unauthorized access to sensitive user data and API keys, potentially enabling further attacks within the Alteryx ecosystem.
If Mitigated
Limited impact with proper access controls and monitoring, though sensitive data exposure remains possible.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2024.2 or later
Vendor Advisory: https://help.alteryx.com/current/en/server/api-overview.html
Restart Required: Yes
Instructions:
1. Upgrade to Alteryx Server 2024.2 or later. 2. Restart the Alteryx Server service. 3. Verify the fix by testing API authorization checks.
🔧 Temporary Workarounds
API Access Restriction
allRestrict API access to trusted IP addresses only using network controls.
Enhanced Monitoring
allImplement detailed logging and monitoring of API requests for suspicious object ID patterns.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Alteryx Server from untrusted networks.
- Deploy a web application firewall (WAF) with IDOR detection rules to block exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Test API endpoints with manipulated MongoDB object IDs while authenticated as a non-admin user to see if unauthorized data is returned.Check Version:
Check Alteryx Server version in the administration console or via the API.Verify Fix Applied:
After patching, repeat the same test to confirm unauthorized access is now properly blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual patterns of API requests with sequential or manipulated object IDs
- Access to API keys from non-admin users
Network Indicators:
- Multiple failed authorization attempts followed by successful data retrieval
- Unusual API request patterns from single users
