RCE Code Injection Fabric Operating System

Description

Brocade Fabric OS versions starting with 9.1.0 have root access removed, however, a local user with admin privilege can potentially execute arbitrary code with full root privileges on Fabric OS versions 9.1.0 through 9.1.1d6.

Analysis

Brocade Fabric OS 9.1.0 through 9.1.1d6 contains a code injection vulnerability that allows local admin users to execute arbitrary code with root privileges despite root access being removed.

Technical Context

The CWE-94 code injection allows admin-level users to inject and execute code with full root privileges. While Fabric OS 9.1.0+ removed root shell access as a security hardening measure, this vulnerability bypasses that restriction.

Affected Products

['Brocade Fabric OS 9.1.0 through 9.1.1d6']

Remediation

Upgrade Fabric OS. Restrict admin access to SAN switches. Monitor for firmware modifications and unusual configuration changes.
