A vulnerability in the authentication mechanism of Brocade Fabric OS versions before Brocade Fabric OS v.9.0.1a, v8.2.3a and v7.4.2h could allow a user to Login with empty password, and invalid password through telnet, ssh and REST.

A vulnerability exists in Broadcom BCM4352 and BCM43684 chips. Any wireless router using BCM4352 and BCM43684 will be affected, such as ASUS AX6100. An attacker may cause a Denial of Service (DoS) to any device connected to BCM4352 or BCM43684 routers via an association or reassociation frame.

The Symantec Advanced Secure Gateway (ASG) and ProxySG web management consoles are susceptible to an authentication bypass vulnerability. An unauthenticated attacker can execute arbitrary CLI commands, view/modify the appliance configuration and policy, and shutdown/restart the appliance.

The OVA version of Brocade SANnav before version 2.1.1 installation with IPv6 networking exposes the docker container ports to the network, increasing the potential attack surface.

The host SSH servers of Brocade Fabric OS before Brocade Fabric OS v7.4.2h, v8.2.1c, v8.2.2, v9.0.0, and Brocade SANnav before v2.1.1 utilize keys of less than 2048 bits, which may be vulnerable to man-in-the-middle attacks and/or insecure SSH communications.

Webtools in Brocade SANnav before version 2.1.1 allows unauthenticated users to make requests to arbitrary hosts due to a misconfiguration; this is commonly referred to as Server-Side Request Forgery (SSRF).

Brocade SANNav before version 2.1.1 contains an information disclosure vulnerability. Successful exploitation of internal server information in the initial login response header.

Brocade Fabric OS prior to v9.0.1a and 8.2.3a and after v9.0.0 and 8.2.2d may observe high CPU load during security scanning, which could lead to a slower response to CLI commands and other operations.

Brocade SANnav before version 2.1.1 allows an authenticated attacker to list directories, and list files without permission. As a result, users without permission can see folders, and hidden files, and can create directories without permission.

Brocade SANnav before v.2.1.0a could allow remote attackers cause a denial-of-service condition due to a lack of proper validation, of the length of user-supplied data as name for custom field name.
