CVE-2026-87685

Arbitrary File Manipulation in Brocade Fabric OS WebTools Allows Admin to Move System Files to World-Readable Locations

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.

Fabric OS Cross‑Fabric Permission Bypass

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.

Brocade Fabric OS Command Injection via Configuration Download Parameter

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.

Cleartext Fabric OS Admin Passwords Trapped in Memory Swap File in Brocade SANnav

A vulnerability in Brocade SANnav before 3.0.1 can have the Brocade Fabric OS switch admin password captured in plaintext within a memory swap file on the server hosting the Brocade SANnav Virtual Machine (VM). This can happen when the SANnav server encounters an Out Of Memory (OOM) condition. The vulnerability could allow an authenticated admin user with access to the server hosting the SANnav to potentially view the memory swap file and access the password(s).

Unauthenticated Disclosure of SAN Fabric Management Topology via Internal Endpoints

An unauthenticated network-based attacker can query specific internal management endpoints on Brocade ASCG versions before 3.5.0 to enumerate the configuration details and state of managed Brocade Fabric OS (FOS) switches. This results in the unauthorized disclosure of the customer's SAN fabric management topology and switch connectivity attributes.

TLS Client Trust Store Modification Enabling MITM

An unauthenticated remote attacker can modify the TLS client trust store in Brocade ASCG versions before 3.5.0. By supplying an unauthorized Certificate Authority (CA) certificate to an unauthenticated management interface, the attacker can cause the system to trust unauthorized certificates, potentially enabling Man-in-the-Middle (MITM) attacks against outbound communications with managed switches and peer nodes.

ASCG Path Traversal Enables Remote Code Execution

When Brocade ASCG before 3.5.0 processes support bundle archives ingested from remote compromised endpoints, the application fails to sanitize path traversal sequences contained within archive entries prior to extraction. An unauthenticated remote attacker capable of sending or intercepting ingested archive files can leverage this flaw to write arbitrary files to restricted locations on the underlying host, potentially leading to remote code execution.

Default Password Leakage Enabling Local Privilege Escalation in Brocade ASCG

Brocade ASCG before 3.5.0 has a well-known Brocade default password embedded in a script distributed to every customer. Any local authenticated user with read access to the installation path can discover this credential and perform privilege escalation on affected Open Virtual Appliance (OVA) deployments, where default configuration settings remain in place.

Improper Input Validation Enables Remote Code Execution in Brocade ASCG

Brocade ASCG before 3.5.0 improperly processes user input by evaluating form data prior to validation. When an authenticated user submits a configuration form, the submitted text could immediately be processed. A malicious actor with basic access can supply crafted input to execute arbitrary code on the server and take control of the application.
