CVE-2025-58383

N/A Unknown

📋 TL;DR

This vulnerability allows administrator-level users on Brocade Fabric OS to execute the bind command, enabling privilege escalation and bypassing security controls to run arbitrary commands. It affects Brocade Fabric OS versions before 9.2.1c2, potentially compromising the security of storage area network (SAN) fabrics.

💻 Affected Systems

Products:
  • Brocade Fabric OS
Versions: All versions before 9.2.1c2
Operating Systems: Fabric OS
Default Config Vulnerable: ⚠️ Yes
Notes: Requires administrator-level access to exploit. Affects SAN switches running vulnerable Fabric OS versions.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of SAN fabric infrastructure, allowing attackers to reconfigure zoning, disrupt storage access, exfiltrate sensitive data, or deploy persistent backdoors across the fabric.

🟠

Likely Case

Privileged insider or compromised administrator account could modify fabric configurations, disrupt storage services, or gain unauthorized access to connected storage systems.

🟢

If Mitigated

Limited impact if strict access controls, network segmentation, and monitoring are in place to detect and prevent unauthorized bind command usage.

🌐 Internet-Facing: LOW - Fabric OS management interfaces should not be directly internet-facing in proper SAN deployments.
🏢 Internal Only: HIGH - Exploitable by any administrator-level user with access to the management interface, posing significant internal threat.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires administrator credentials. The bind command misuse is documented in the advisory.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 9.2.1c2 or later

Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36878

Restart Required: Yes

Instructions:

1. Download Fabric OS 9.2.1c2 or later from Broadcom support portal. 2. Backup current configuration. 3. Apply firmware update following vendor documentation. 4. Reboot switch. 5. Verify successful upgrade and functionality.

🔧 Temporary Workarounds

Restrict bind command usage

all

Implement role-based access control to limit who can execute bind commands

Configure via Fabric OS CLI or management interface

Enhanced monitoring

all

Monitor and alert on bind command usage in logs

Enable detailed audit logging for command execution

🧯 If You Can't Patch

  • Implement strict access controls and least privilege for administrator accounts
  • Monitor and audit all bind command usage with immediate alerting for suspicious activity

🔍 How to Verify

Check if Vulnerable:

Check Fabric OS version: 'version' command in CLI. If version is earlier than 9.2.1c2, system is vulnerable.

Check Version:

version

Verify Fix Applied:

After patching, run 'version' command to confirm version is 9.2.1c2 or later.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized or suspicious bind command executions
  • Privilege escalation attempts in audit logs

Network Indicators:

  • Unexpected zoning changes
  • Unusual management interface activity

SIEM Query:

Search for 'bind' command executions from non-standard administrator accounts or at unusual times
