- CWE-187 - Partial Comparison
Summary
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.

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.

CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
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.

- CWE-15 - External Control of System or Configuration Setting
Summary
A privilege escalation vulnerability exists in the internal Command-Line Interface (CLI) authorization handling mechanism of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user or local process that can manipulate the process execution environment can bypass Role-Based Access Control (RBAC) validation checks. Successful exploitation allows an attacker to elevate privileges to root

CWE
- CWE-306 - Missing Authentication for Critical Function
Summary
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.

CWE
- CWE-290 - Authentication Bypass by Spoofing
Summary
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.

CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
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.

CWE
- CWE-88 - Improper Neutralization of Argument Delimiters or Special Sequences in Commands ('Argument Injection')
Summary
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.

CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
An OS command injection vulnerability exists in the time and zone management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When updating system timezone settings via the REST API or configuration download routines, the system fails to sanitize input values before processing them in underlying shell execution routines. An authenticated user with low-privilege administrative access can exploit this vulnerability by submitting a crafted timezone string containing shell metacharacters. Successful exploitation allows the attacker to escape the restricted management environment and execute arbitrary shell commands with elevated privileges.

- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
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.

CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
A local privilege escalation vulnerability exists in the system logging daemon of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Insufficient access controls on internal inter-process communication (IPC) channels allow an unprivileged local user to submit malformed logging configurations. Due to improper input sanitization during configuration file generation, an attacker can inject arbitrary directives that execute with elevated privileges when the logging service reloads, leading to local privilege escalation.

CWE
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
An OS command injection vulnerability exists in maintenance command-line diagnostic utilities on Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. The binary fails to sanitize user-supplied input options when invoking underlying system commands through a shell interpreter. A privileged user with maintenance account access can exploit this issue by supplying crafted parameters, which results in arbitrary OS command execution with root privileges.

Summary
An authorization and input validation vulnerability exists in Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user with restricted privileges in one Virtual Fabric can exploit this issue by submitting a specially crafted request containing an arbitrary fabric identifier. This allows the user to perform unauthorized cross-fabric operations and view configuration details within tenants/Virtual Fabrics to which they have not been granted access.

CWE
- CWE-73 - External Control of File Name or Path
Summary
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.

- CWE-77 - Command Injection
Summary
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.

CWE
- CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Summary
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.

CWE
- CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Summary
A race condition vulnerability exists in the request processing logic of the REST management interface on Brocade Fabric OS versions before 10.0.1. When handling concurrent incoming network management FCIP requests, a timing window exists between when a request populates the address variable and when the service constructs and returns the response context. As a result, the first request adopts the modified context, causing the service to return sensitive management details or configuration data belonging to the second context back to the original requester.

CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
Summary
A memory buffer overflow vulnerability exists in the internal diagnostic and route validation routines used by the Fabric Shortest Path First (FSPF) protocol component of Brocade Fabric OS versions before 10.0.1. While this code path is part of internal diagnostic functionality and is not directly accessible via standard user interfaces or CLI management commands, an input processing flaw allows incoming or internally routed diagnostic state payloads to exceed allocated memory boundaries. An attacker that is able to chain or link other vulnerabilities to exploit this internal diagnostic could cause a heap- or stack-based memory overrun, resulting in a daemon crash (Denial of Service) or potential arbitrary code execution within the context of the routing daemon.

CWE
- CWE-121 - Stack-based Buffer Overflow
Summary
A stack-based buffer overflow vulnerability exists in the diagnostic execution utility of Brocade Fabric OS versions before 10.0.1. When processing command arguments for diagnostic operations, the utility tokenizes user-supplied input into an internal argument array without enforcing boundary checks on the maximum array capacity. An authenticated user with administrative access can exploit this vulnerability by supplying a crafted diagnostic command string containing an excessive number of tokenized arguments. This leads to a memory overwrite resulting in a denial of service (process crash).

CWE
- CWE-121 - Stack-based Buffer Overflow
Summary
A stack-based buffer overflow vulnerability exists in the Internet Key Exchange (IKEv2) protocol handler on Brocade Fabric OS versions before 10.0.1. The vulnerability occurs when processing initial IKE key exchange requests on extension switches or blades running IPsec-enabled Fibre Channel over IP (FCIP) circuits. An unauthenticated remote attacker can exploit this vulnerability by sending a single, specifically crafted UDP packet (Port 500) containing an oversized Nonce payload. Successful exploitation results in a denial of service (data-plane process crash)

- CWE-532 - Insertion of Sensitive Information into Log File
Summary
An information disclosure vulnerability exists in the SupportLink diagnostic collection utilities of Brocade Fabric OS versions before 10.0.1. When SupportLink is configured to use an authenticated HTTP proxy, the system stores the full proxy URL. Anyone with access to the diagnostic support bundle, such as support personnel or users with access to file shares where support bundles are stored, can extract these cleartext proxy credentials.

CWE
- CWE-290 - Authentication Bypass by Spoofing
Summary
An authorization logic vulnerability exists in the Brocade Fabric OS versions before 10.0.1 REST API gateway. The internal gate guarding restricted management endpoints relies exclusively on client-controlled HTTP headers. An authenticated user with any valid REST session can spoof these headers to gain unauthorized access to internal management endpoints. This allows low-privilege users to view sensitive chassis metadata, hardware memory patrolling state, and firmware integrity audit logs.
