CVE-2025-1053
📋 TL;DR
During SANnav installation or upgrade error conditions, the encryption key can be written to and retrieved from a supportsave file. Attackers with privileged database access could use this key to decrypt passwords used by SANnav. This affects Brocade SANnav deployments where supportsave files are accessible.
💻 Affected Systems
- Brocade SANnav
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of SANnav credentials leading to unauthorized access to SAN management infrastructure, potential data exfiltration, and disruption of storage operations.
Likely Case
Privileged attackers with database access obtain encryption keys and decrypt stored passwords, gaining elevated access within the SANnav environment.
If Mitigated
Limited impact due to restricted database access, proper supportsave file handling, and encryption key rotation.
🎯 Exploit Status
Requires privileged database access and ability to obtain supportsave files; exploitation depends on specific error conditions during installation/upgrade.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Broadcom advisory for specific fixed versions
Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/25399
Restart Required: Yes
Instructions:
1. Review Broadcom advisory for affected versions. 2. Apply recommended patches/updates from Broadcom. 3. Restart SANnav services as required. 4. Verify encryption key handling in supportsave files.
🔧 Temporary Workarounds
Restrict supportsave file access
linuxLimit access to supportsave files to authorized personnel only and ensure proper file permissions.
chmod 600 /path/to/supportsave/files
chown root:root /path/to/supportsave/files
Monitor database access
allImplement strict access controls and monitoring for SANnav database privileged accounts.
🧯 If You Can't Patch
- Implement strict access controls on SANnav database and supportsave files
- Monitor for unauthorized access attempts and review supportsave file generation logs
🔍 How to Verify
Check if Vulnerable:
Check SANnav version against Broadcom advisory; review supportsave files for encryption key exposure during error conditions.Check Version:
Check SANnav management interface or documentation for version command specific to your deploymentVerify Fix Applied:
Verify SANnav is updated to patched version; test supportsave generation during error conditions to ensure encryption keys are not exposed.📡 Detection & Monitoring
