CVE-2025-26515

7.5 HIGH

📋 TL;DR

An unauthenticated attacker can exploit a Server-Side Request Forgery (SSRF) vulnerability in StorageGRID to change passwords for Grid Manager or Tenant Manager users when Single Sign-on is disabled. This affects StorageGRID versions before 11.8.0.15 and 11.9.0.8 without SSO enabled. The vulnerability allows complete account takeover of administrative users.

💻 Affected Systems

Products:
  • NetApp StorageGRID (formerly StorageGRID Webscale)
Versions: All versions prior to 11.8.0.15 and 11.9.0.8
Operating Systems: All supported StorageGRID platforms
Default Config Vulnerable: ✅ No
Notes: Only vulnerable when Single Sign-on (SSO) is NOT enabled. Systems with SSO enabled are not affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of StorageGRID management infrastructure, allowing attacker to reset all administrative passwords, gain full control over storage systems, and potentially exfiltrate or destroy data.

🟠

Likely Case

Attacker gains administrative access to StorageGRID management interface, enabling configuration changes, user management, and potential data access.

🟢

If Mitigated

With SSO enabled, the vulnerability is not exploitable, maintaining normal security posture.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires SSRF knowledge and understanding of StorageGRID's internal API endpoints.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 11.8.0.15 or 11.9.0.8

Vendor Advisory: https://security.netapp.com/advisory/NTAP-20250910-0002

Restart Required: Yes

Instructions:

1. Backup current configuration. 2. Download appropriate patch version from NetApp support site. 3. Apply patch following StorageGRID upgrade procedures. 4. Restart affected services. 5. Verify patch installation and functionality.

🔧 Temporary Workarounds

Enable Single Sign-on (SSO)

all

Enabling SSO completely mitigates the vulnerability as it prevents the unauthenticated attack vector.

Network Segmentation

all

Restrict access to StorageGRID management interfaces to trusted networks only.

🧯 If You Can't Patch

  • Enable Single Sign-on (SSO) immediately if not already enabled
  • Implement strict network access controls to limit StorageGRID management interface exposure

🔍 How to Verify

Check if Vulnerable:

Check StorageGRID version via admin interface or CLI. If version is below 11.8.0.15 or 11.9.0.8 AND SSO is disabled, system is vulnerable.

Check Version:

ssh admin@storagegrid-node 'sudo storagegrid node status' or check via StorageGRID Admin Node web interface

Verify 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) via admin interface or CLI.

📡 Detection & Monitoring

Log Indicators:

  • Unusual password reset requests
  • Failed authentication attempts followed by successful password changes
  • SSRF-related error messages in application logs

Network Indicators:

  • HTTP requests to internal endpoints from external sources
  • Unusual API calls to user management endpoints

SIEM Query:

source="storagegrid" AND (event_type="password_reset" OR event_type="user_modify") AND src_ip NOT IN trusted_networks
