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.
Several commands in Brocade Fabric OS before Brocade Fabric OS v.9.0.1e, and v9.1.0 use unsafe string functions to process user input. Authenticated local attackers could abuse these vulnerabilities to exploit stack-based buffer overflows, allowing arbitrary code execution as the root user account.
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.
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.
A vulnerability in the Brocade Fabric OS before Brocade Fabric OS v9.0.1a, v8.2.3, v8.2.0_CBN4, and v7.4.2h could allow an authenticated CLI user to abuse the history command to write arbitrary content to files.
Brocade Fabric OS before Brocade Fabric OS v8.2.1c, v8.1.2h, and all versions of Brocade Fabric OS v8.0.x and v7.x contain documented hard-coded credentials, which could allow attackers to gain access to the system.
The command ipfilter in Brocade Fabric OS before Brocade Fabric OS v.9.0.1a, v8.2.3, and v8.2.0_CBN4, 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.
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.
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 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.
