CVE-2025-9711
📋 TL;DR
This vulnerability allows local authenticated users on Brocade Fabric OS systems to escalate their privileges to root level using specific commands. It affects Brocade SAN switch administrators and operators who have legitimate access to the system. The vulnerability exists in the export functionality of seccertmgmt and seccryptocfg commands.
💻 Affected Systems
- Brocade Fabric OS
⚠️ Risk & Real-World Impact
Worst Case
An authenticated malicious insider or compromised account gains full root access to the SAN switch, enabling complete control over storage network configuration, data interception, and potential denial of service.
Likely Case
Privileged administrators accidentally or intentionally use the vulnerable commands to gain unnecessary root access, potentially bypassing security controls and audit trails.
If Mitigated
With proper access controls and monitoring, the impact is limited to authorized administrators who already have significant system access.
🎯 Exploit Status
Exploitation requires authenticated access to the switch CLI and knowledge of the vulnerable commands. The advisory suggests the exploit is straightforward for users with legitimate access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.2.1c3
Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36852
Restart Required: Yes
Instructions:
1. Download Fabric OS 9.2.1c3 from Broadcom support portal. 2. Upload firmware to switch. 3. Install firmware using 'firmwareDownload' command. 4. Reboot switch to activate new version.
🔧 Temporary Workarounds
Restrict command access
allLimit access to seccertmgmt and seccryptocfg commands using role-based access controls
userconfig --modify <username> -r <restricted_role>
roleconfig --show <role_name>
Monitor command usage
allEnable audit logging for seccertmgmt and seccryptocfg commands
auditcfg --enable audit
auditcfg --set seccertmgmt
auditcfg --set seccryptocfg
🧯 If You Can't Patch
- Implement strict role-based access control to limit who can execute seccertmgmt and seccryptocfg commands
- Enable comprehensive audit logging and monitor for unauthorized privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check Fabric OS version with 'version' command. If version is earlier than 9.2.1c3, system is vulnerable.
Check Version:
version
Verify Fix Applied:
After patching, run 'version' command and confirm version is 9.2.1c3 or later.
