Brocade ASCG vulnerabilities

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.

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.

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.

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.

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.

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.

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.

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.

Vulnerability in the data collection service of Brocade ASCG before 3.5.0. An API endpoint fails to perform authentication or authorization, allowing an attacker with network access to establish SSH connections to arbitrary hosts and execute arbitrary system commands, turning the appliance into an unauthenticated proxy or execution vector.

A vulnerability in Brocade ASCG 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 protect inter-node communication protocols. An attacker who extracts this key can decrypt stored management credentials or craft forged administrative synchronization messages.

A critical security vulnerability in Brocade ASCG before 3.5.0. The HTTPS service fails to enforce authentication or access control on incoming requests. An unauthenticated attacker with network access can issue control commands, alter cluster states, and modify system configurations, leading to complete compromise of the streaming service control plane.

An Improper Input Validation vulnerability in Brocade ASCG before v3.0 affects registered case credentials. A local authenticated user can provide invalid inputs like special characters, leading to a Denial of Service (DoS) when collecting 'supportsave' from a Brocade Switch.

In Brocade ASCG before v3.0, several security-related HTTP headers were missing in various URL paths, aiding unauthenticated attackers to perform attacks such as Cross-Site Scripting, Clickjacking, Information disclosure, and more.
