An Improper Check for Unusual or Exceptional Conditions vulnerability in Brocade Fabric OS before 9.2.2.a could allow an authenticated, network-based attacker to cause a Denial-of-Service (DoS). The vulnerability is encountered when supportsave is invoked remotely, using ssh command or SANnav inline ssh, and the corresponding ssh session is terminated with Control C (^c ) before supportsave completion. This issue affects Brocade Fabric OS 9.0.0 through 9.2.2

A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5 could allow a local authenticated attacker to export out sensitive files with “seccryptocfg”, “configupload”.

A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, and 7.4.2j could allow a local authenticated user to break out of restricted shells with “set context” and escalate privileges.

Brocade Fabric OS Web Application services before Brocade Fabric v9.1.0, v9.0.1e, v8.2.3c, v7.4.2j store server and user passwords in the debug statements. This could allow a local user to extract the passwords from a debug file.

Brocade Webtools in Brocade Fabric OS versions before Brocade Fabric OS versions v9.1.1, v9.0.1e, and v8.2.3c could allow a low privilege webtools, user, to gain elevated admin rights, or privileges, beyond what is intended or entitled for that user. By exploiting this vulnerability, a user whose role is not an admin can create a new user with an admin role using the operator session id. The issue was replicated after intercepting the admin, and operator authorization headers sent unencrypted and editing a user addition request to use the operator's authorization header.

A vulnerability in fabseg.c.h libraries of all Brocade Fabric OS versions before Brocade Fabric OS v9.1.1, v9.0.1e, v8.2.3c, v8.2.0cbn5, 7.4.2j could allow local authenticated attackers to exploit stack-based buffer overflows and execute arbitrary code as the root user account.

A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, 7.4.2.j could allow a remote authenticated attacker to perform stack buffer overflow using in “firmwaredownload” and “diagshow” commands.

A privilege escalation vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, could allow a local authenticated user to escalate its privilege to root using switch commands “supportlink”, “firmwaredownload”, “portcfgupload, license, and “fosexec”.

An information disclosure vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5, 7.4.2.j could allow a local authenticated attacker to read sensitive files using switch commands “configshow” and “supportlink”.

Brocade Web Interface in Brocade Fabric OS v9.x and before v9.2.0 does not properly represent the portName to the user if the portName contains reserved characters. This could allow an authenticated user to alter the UI of the Brocade Switch and change ports display.

Remote code execution (RCE) vulnerability in Brocade Fabric OS after v9.0 and before v9.2.0 could allow an attacker to execute arbitrary code and use this to gain root access to the Brocade switch.

A vulnerability in the web interface in Brocade Fabric OS before v9.2.1, v9.2.0b, and v9.1.1d prints encoded session passwords on session storage for Virtual Fabric platforms. This could allow an authenticated user to view other users' session encoded passwords.

A vulnerability in the Brocade Fabric OS before Brocade Fabric OS v9.0.1a, v8.2.3, v8.2.0CBN4, and v7.4.2h could allow an authenticated CLI user to abuse the history command to write arbitrary content to files.

The command ipfilter in Brocade Fabric OS before Brocade Fabric OS v.9.0.1a, v8.2.3, and v8.2.0CBN4, and v7.4.2h uses unsafe string function to process user input. Authenticated attackers can abuse this vulnerability to exploit stack-based buffer overflows, allowing execution of arbitrary code as the root user account.

ntermittent authorization failure in aaa tacacs+ with Brocade Fabric OS versions before Brocade Fabric OS v9.0.1b and after 9.0.0, also in Brocade Fabric OS before Brocade Fabric OS v8.2.3a and after v8.2.0 could cause a user with a valid account to be unable to log into the switch.

The request handling functions in web management interface of Brocade Fabric OS versions before v9.0.1a, v8.2.3a, and v7.4.2h do not properly handle malformed user input, resulting in a service crash. An authenticated attacker could use this weakness to cause the FOS HTTP application handler to crash, requiring a reboot.

The function that is used to parse the Authentication header in Brocade Fabric OS Web application service before Brocade Fabric OS v9.0.1a and v8.2.3a fails to properly process a malformed authentication header from the client, resulting in reading memory addresses outside the intended range. An unauthenticated attacker could discover a request, which could bypass the authentication process.

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.

The Web application of Brocade Fabric OS before versions Brocade Fabric OS v9.0.1a and v8.2.3a contains debug statements that expose sensitive information to the program's standard output device. An attacker who has compromised the FOS system may utilize this weakness to capture sensitive information, such as user credentials.

The Brocade Fabric OS Commands “configupload” and “configdownload” before Brocade Fabric OS v9.1.1c, v8.2.3d, v9.2.0 print scp, sftp, ftp servers passwords in supportsave. This could allow a remote authenticated attacker to access sensitive information.
