Vulnerabilidades do Broadcom Fabric Operating System

A buffer overflow vulnerability exists in the WebTools administrative interface handling configuration download or file transfer operations of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user with permissions to perform configuration downloads using remote server profiles can overflow stack buffers causing a crash of the weblinker daemon.

A command injection vulnerability exists in the WebTools administrative interface handling configuration download or file transfer operations of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user with permissions to perform configuration downloads using remote server profiles can supply malicious parameter strings to execute arbitrary shell commands on the switch with root privileges

An OS command injection vulnerability exists in the REST API management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 allows an authenticated, high-privileged remote attacker to execute arbitrary system commands with root permissions. An attacker with administrative privileges to configure SSH known host settings can supply specially crafted parameter values containing shell metacharacters to trigger command execution on the host system.

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 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.

Brocade Fabric versions before 9.2.2d and 10.0.0 through 10.0.0a1 handling of specific download protocols utilizes unsanitized parameter strings. When processing upgrade requests, parameters are converted into system command strings and executed through a system shell interface. Because control characters and shell metacharacters in fields like the host or file path are not stripped or sanitized, an attacker can execute arbitrary shell commands with the firmware management daemon's elevated privileges.

Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 directly accepts Apache configuration file data during service setup or re-initialization. An attacker capable of corrupting the configuration structure will prevent the web management service from starting or recovering during service bring-up, leading to a persistent Denial of Service (DoS) of the administrative web interface.

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 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 input validation vulnerability exists in the security certificate management component of the Brocade Fabric OS administrative management API. When processing certificate management operations, user-supplied certificate identifiers are handled without adequate sanitization prior to execution in external system routines. An authenticated attacker with privileges to perform certificate deletion requests can leverage this flaw to execute arbitrary system commands with the privileges of the underlying management daemon. This vulnerability affects Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1.

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.

An OS command injection vulnerability exists in the configuration management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When performing a configuration download operation, the management daemon will relay configuration parameters, user-supplied relay host strings, and filenames directly to an internal utility script without sufficient character set validation. Because the local utility fails to sanitize shell metacharacters before processing them in a system shell command, a malicious or compromised configuration file can cause arbitrary operating system commands to be executed on a remote local switch when an administrator initiates a configuration download.

An argument injection vulnerability exists in the configuration management command-line utility of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When executing configuration viewing commands with search pattern filters, the utility fails to sanitize user-supplied search string options before passing them to internal search commands. An authenticated user with low-privilege administrative access can exploit this vulnerability to read arbitrary files on the local operating system, including sensitive configuration files, system password hashes and system secrets.
