CVE-2025-26517
📋 TL;DR
This CVE describes a privilege escalation vulnerability in NetApp StorageGRID where authenticated attackers can discover Grid node names and IP addresses or modify Storage Grades. The vulnerability affects StorageGRID versions before 11.8.0.15 and 11.9.0.8. Attackers need authentication but not authorization for the specific actions.
💻 Affected Systems
- NetApp StorageGRID (formerly StorageGRID Webscale)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could map the entire StorageGRID infrastructure, modify storage configurations to disrupt operations or exfiltrate data, and potentially use discovered information for further attacks.
Likely Case
An authenticated user with limited privileges could discover sensitive infrastructure details and make unauthorized changes to storage configurations, potentially affecting data availability and integrity.
If Mitigated
With proper access controls and monitoring, the impact is limited to information disclosure about node names/IPs, with configuration changes being detected and rolled back.
🎯 Exploit Status
Exploitation requires authenticated access to the StorageGRID system. The attacker needs to understand the StorageGRID API or interface to perform the unauthorized actions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 11.8.0.15 or 11.9.0.8
Vendor Advisory: https://security.netapp.com/advisory/NTAP-20250910-0004
Restart Required: No
Instructions:
1. Backup current configuration. 2. Download appropriate patch version from NetApp support site. 3. Apply patch using StorageGRID update procedures. 4. Verify system functionality post-update.
🔧 Temporary Workarounds
Restrict Access Controls
allImplement strict access controls to limit which authenticated users can access StorageGRID management interfaces.
Network Segmentation
allIsolate StorageGRID management interfaces from general network access.
🧯 If You Can't Patch
- Implement strict principle of least privilege for all StorageGRID user accounts
- Enable comprehensive logging and monitoring of all StorageGRID configuration changes and access attempts
🔍 How to Verify
Check if Vulnerable:
Check StorageGRID version via Grid Manager UI or API. If version is below 11.8.0.15 (for 11.8.x) or below 11.9.0.8 (for 11.9.x), system is vulnerable.Check Version:
Check via Grid Manager UI: System > About, or via API: GET /api/v3/grid/versionVerify Fix Applied:
Verify version is 11.8.0.15 or higher (for 11.8.x) or 11.9.0.8 or higher (for 11.9.x) after applying patch.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to node discovery endpoints
- Unexpected modifications to Storage Grade configurations
- Authentication logs showing users accessing privileged functions
Network Indicators:
- Unusual API calls to node discovery endpoints
- Traffic patterns indicating infrastructure mapping
SIEM Query:
