7.6CVE-2026-87425broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.10%
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.
5.3CVE-2026-87426broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.15%
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.
8.8CVE-2026-87424broadcombrocade_active_support_connectivity_gateway+1
EPSS score

A vulnerability in the SupportLink API authentication component of Brocade ASCG versions prior to 3.5.0 allows an attacker to bypass authentication across deployments due to the use of a hard coded cryptographic key.
8.4CVE-2026-87428broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.10%
In Brocade ASCG before 3.5.0, a  local unauthorized user on the ASCG VM who can issue a request to the SANnav host network namespace can extract stored management credentials for onboarded SANnav instances and compromise connected Brocade SANnav servers or managed Brocade Fibre Channel switches.
8.4CVE-2026-85422broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.10%
A vulnerability in Brocade ASCG version before 3.5.0 could allow an attacker to obtain a static cryptographic key hardcoded into the software binaries to secure sensitive data at rest and to protect inter-node communication protocols. An attacker who extracts this key can decrypt stored management credentials or craft forged administrative synchronization messages.
7.8CVE-2026-85488broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.09%
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.
8.6CVE-2026-85486broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.29%
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.
8.8CVE-2026-85489broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.21%
An authentication flaw exists in the Brocade ASCG administrative management service component. An unauthenticated network user can issue direct API requests to perform privileged actions, including accessing sensitive system configuration mapping data, modifying managed device inventories, and altering operational settings. This vulnerability affects all versions of Brocade ASCG before 3.5.0.
8.8CVE-2026-85423broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.24%
A vulnerability has been identified in the data collection service of Brocade ASCG versions before 3.5.0. An API endpoint within the data collector service fails to perform authentication or authorization checks on incoming requests. An attacker with network access to the service can instruct the application to establish SSH connections to arbitrary hosts and execute arbitrary system commands, effectively turning the appliance into an unauthenticated proxy or execution vector.
8.8CVE-2026-85421broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.22%
A critical security vulnerability has been identified in Brocade ASCG versions before 3.5.0. The HTTPS service fails to properly enforce authentication or access control checks on incoming requests. An unauthenticated attacker with network access can issue control commands, alter cluster states, and modify system configurations, leading to a complete compromise of the streaming service control plane.
8.8CVE-2026-85490broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.31%
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.
8.8CVE-2026-85487broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.24%
A path traversal vulnerability exists in the HTTP service component of Brocade ASCG versions before 3.5.0. An unauthenticated attacker on the local network could send a manipulated API request to the service endpoint bypassing path restrictions to arbitrary file read, file write, or file deletion operations.
6.8CVE-2023-5649broadcombrocade_active_support_connectivity_gateway+1
EPSS score
0.09%
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.
