OS Command Injection in Brocade Fabric OS

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: Brocade Communications Systems, LLC

Description
Multiple OS Command Injection vulnerabilities exist in the management interface and session processing routines of Brocade Fabric OS versions before 10.0.1. Input processing flaws during remote management connection validation and session verification for directory-based user accounts allow untrusted input containing shell metacharacters to reach internal system execution wrappers. An authenticated user or a compromised directory service account can exploit these vulnerabilities to execute arbitrary operating system commands with elevated privileges on the target device.

Executive Summary

This vulnerability involves multiple OS Command Injection flaws in Brocade Fabric OS versions before 10.0.1. It occurs during remote management connection validation and session verification for directory-based user accounts. Untrusted input with shell metacharacters can bypass input processing and reach system execution wrappers, allowing attackers to run arbitrary commands with elevated privileges.

Detection Guidance

Detecting this vulnerability requires checking Brocade Fabric OS versions before 10.0.1. Verify the OS version using commands like 'firmware show' or 'version' on the Brocade device. Inspect logs for unusual command execution patterns or shell metacharacters in input fields of the management interface.

Impact Analysis

An authenticated user or compromised directory service account could exploit this to execute arbitrary OS commands with high privileges on the device. This may lead to unauthorized access, data breaches, system compromise, or disruption of services.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating confidentiality and integrity requirements in GDPR and HIPAA. Non-compliance may result in legal penalties, fines, or reputational damage due to exposed sensitive data.

Mitigation Strategies

Immediately upgrade Brocade Fabric OS to version 10.0.1 or later. Disable remote management interfaces if not essential. Restrict access to authenticated users only and audit directory-based user accounts for unauthorized modifications. Monitor network traffic for suspicious activity targeting the management interface.
