Security Vulnerabilities
An authentication bypass and command injection vulnerability exists in the inter-switch remote execution service of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When processing remote command execution IPC frames across the fabric, the receiving switch processes these commands at an elevated processing level without proper verification of transmitted parameters. This allows an attacker on a single fabric-connected switch to escalate privileges and execute arbitrary root commands locally or across other managed fabric members where remote execution functionality is enabled.

A session context forgery vulnerability exists in the web management daemon of Brocade Fabric OS versions 9.2.2d and 10.0.0 through 10.0.0a1. When processing local inter-process communication (IPC) storage callbacks, the service accepts and registers session structures including administrative role permissions, user identifiers, and authorization flags—without verifying the identity or authenticity of the sending process. An attacker can obtain elevated administrative privileges on the web management interface without legitimate authentication.

An OS command injection vulnerability exists in the account management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When an administrator initiates an account deletion, the system invokes an internal maintenance routine to clean up cryptographic keys associated with the target account. Malformed account names previously accepted by Fabric OS can cause the execution of embedded shell metacharacters, triggering command injection.

An authentication logic and privilege escalation vulnerability exists in the account management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Under specific conditions, an authenticated user can bypass authorization restrictions intended to prevent modifying another account's access privileges. Exploitation allows a lower-privileged user to assign administrative roles to a target account, leading to localized privilege escalation.

In Brocade ASCG before Brocade ASCG v3.0, several security-related HTTP Headers were missing in various Brocade ASCG URL paths, aiding unauthenticated attackers to perform attacks such as Cross-Site Scripting, Clickjacking, Information disclosure, and more.

An Improper Input Validation vulnerability for the registered case credentials in Brocade ASCG before v3.0 could allow a local authenticated user to provide invalid inputs like special characters leading to a Denial of Service (DoS) when collecting “supportsave” from a Brocade Switch.

A logic vulnerability in Brocade Fabric OS versions before 10.0.1 web management framework allows an authenticated, low-privileged user to bypass inner Role-Based Access Control (RBAC) checks under specific environmental conditions. Successful exploitation lowers the system authorization mode for the active session context, allowing access to restricted configuration settings intended exclusively for administrative roles.

An arbitrary file and directory deletion vulnerability exists in the REST API management interface handling USB storage operations on Brocade Fabric OS versions before 10.0.1. An authenticated user possessing USB management privileges can manipulate requested target paths to delete arbitrary files or directories on the switch's local root filesystem, bypassing intended USB mount point boundaries.

A race condition and thread-safety vulnerability exists in the web management daemon of Brocade Fabric OS versions before 10.0.1. When handling user authentication requests across a multi-threaded execution pool, this race condition causes PAM modules to process stale or incorrect client IP addresses and switch context numbers. This leads to inaccurate audit records and potential access control bypasses where AAA evaluation or Calling-Station-ID ACL policies rely on client IP attributes.

An arbitrary file manipulation vulnerability exists in the WebTools management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When processing configuration transfer requests, the application fails to properly validate and sanitize a user-supplied status file path parameter. An authenticated administrative user can exploit this issue by submitting a specially crafted status file parameter, causing the underlying process to move an arbitrary system file to a predictable, world-readable temporary directory. This can lead to persistent Denial of Service (DoS), critical system file destruction, host compromise, or sensitive data leakage.
