CVE-2026-87674 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 7.8 High
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.
CVE-2026-87685 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 6.8 Medium
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.
CVE-2026-87687 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 7.3 High
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.
CVE-2026-87675 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 6.8 Medium
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.
CVE-2026-87676 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 5.7 Medium
A stack-based buffer overflow vulnerability exists in the security library component of Brocade Fabric OS versions before 10.0.1. When parsing uploaded X.509 PEM certificates for management display, the system improperly validates the length of the Authority Key Identifier (AKI) extension before copying string tokens into an internal memory buffer. An authenticated user with administrative privileges to import custom certificates can supply a certificate containing an intentionally oversized AKI extension. When the system processes or renders the certificate attributes, this can trigger a stack memory corruption leading to a denial-of-service (DoS) condition by crashing the management daemon.
CVE-2026-87678 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 5.2 Medium
An input validation and output encoding vulnerability exists in the web management interface of Brocade Fabric OS versions before 10.0.1. When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator—or an attacker capable of supplying crafted FA configuration files during an import routine—can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.
CVE-2026-87684 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 9.8 Critical
A stack-based buffer overflow vulnerability exists in the SNMP daemon request handling of Brocade Fabric versions before 10.0.1. When processing an incoming SNMPv3 packet, an internal statistics gathering handler copies user-supplied context name data into a fixed-size buffer without properly validating the length of the string. A remote, unauthenticated attacker (under default configuration) can exploit this vulnerability by sending a specially crafted SNMPv3 packet, leading to memory corruption, daemon crash (Denial of Service), or potential arbitrary code execution.
CVE-2026-87686 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 4.3 Medium
An authentication and access control bypass vulnerability exists in the web server management interface of Brocade Fabric OS versions before 10.0.1. The web dispatcher routine evaluates internal management VLAN trust decisions using the client-supplied HTTP host header instead of the actual socket transport layer source IP address. Successful exploitation allows the attacker to bypass IP-filtering access control lists (ACLs) and obtain sensitive device metadata (such as model, serial number, hardware revision, and firmware version) without authentication.
CVE-2026-94578 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 8.8 High
Brocade Fabric OS versions before 10.0.1 contain an authorization logic vulnerability in the AAA (Authentication, Authorization, and Accounting) integration framework allows remote authenticated users to gain root-equivalent chassis access controls. By returning specific, crafted Vendor-Specific Attributes (VSAs) or directory claims from an external identity provider (such as RADIUS, LDAP, TACACS+, or Federated IDP), an account can bypass administrative role restriction checks during session establishment.
CVE-2026-94575 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 5.7 Medium
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.
CVE-2026-94582 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 7.8 High
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.
CVE-2026-94583 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 2.6 Low
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.
CVE-2026-87672 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-14 5.5 Medium
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.
CVE-2026-87682 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 8.8 High
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.
CVE-2026-87683 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 8.8 High
Multiple stack-based buffer overflow vulnerabilities exist in the REST API management component of Brocade Fabric OS versions prior to 10.0.1. When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.
CVE-2026-87659 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 9.8 Critical
A critical authorization bypass vulnerability exists in the Management Server handling of Brocade Fabric OS versions before 10.0.1. A compromised switch connected to the fabric can transmit crafted inband Fibre Channel vendor-unique CT (Common Transport) management requests to bypass administrative authentication. Successful exploitation allows an unauthorized peer switch to execute administrative actions on the target device, including resetting administrative passwords, initiating system reboots, and triggering firmware downloads.
CVE-2026-87665 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 7.5 High
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)
CVE-2026-87668 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 6.5 Medium
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).
CVE-2026-87669 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 4.3 Medium
A missing authorization check in Brocade Fabric OS versions before 10.0.1 REST API interface of affected platform releases allows an authenticated user, regardless of their assigned role or administrative scope, to retrieve complete Monitoring and Alerting Policy Suite (MAPS) violation data across all logical switches. An attacker with low-privilege API access can leverage this endpoint to dump chassis-wide system health metrics, port performance violations, and configuration data without appropriate privileges.
CVE-2026-87670 2 Broadcom, Brocade 2 Fabric Operating System, Fabric Os 2026-10-13 4.3 Medium
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.
