Brocade Fabric OS versions before 8.2.3e2, versions 9.0.0 through 9.2.0c, and 9.2.1 through 9.2.1a can capture the SFTP/FTP server password used for a firmware download operation initiated by SANnav or through WebEM in a weblinker core dump that is later captured via supportsave.

A vulnerability in Brocade Fabric OS versions before 9.2.2 could allow man-in-the-middle attackers to conduct remote Service Session Hijacking that may arise from the attacker's ability to forge an SSH key while the Brocade Fabric OS Switch is performing various remote operations initiated by a switch admin.

A vulnerability in the default configuration of the Simple Network Management Protocol (SNMP) feature of Brocade Fabric OS versions before v9.0.0 could allow an authenticated, remote attacker to read data from an affected device via SNMP. The vulnerability is due to hard-coded, default community string in the configuration file for the SNMP daemon. An attacker could exploit this vulnerability by using the static community string in SNMP version 1 queries to an affected device.

A vulnerability in a password management API in Brocade Fabric OS versions before v9.2.1, v9.2.0b, v9.1.1d, and v8.2.3e prints sensitive information in log files. This could allow an authenticated user to view the server passwords for protocols such as scp and sftp. Detail. When the firmwaredownload command is incorrectly entered or points to an erroneous file, the firmware download log captures the failed command, including any password entered in the command line.

Brocade Fabric OS (FOS) hardware platforms running any version of Brocade Fabric OS software, which supports the license string format; contain cryptographic issues that could allow for the installation of forged or fraudulent license keys. This would allow attackers or a malicious party to forge a counterfeit license key that the Brocade Fabric OS platform would authenticate and activate as if it were a legitimate license key.

In Brocade Fabric OS before v9.2.0a, a local authenticated privileged user can trigger a buffer overflow condition, leading to a kernel panic with large input to buffers in the portcfgfportbuffers command.

Brocade Fabric OS versions before Brocade Fabric OS v9.1.1c, and v9.2.0 Could allow an authenticated, local user with knowledge of full path names inside Brocade Fabric OS to execute any command regardless of assigned privilege. Starting with Fabric OS v9.1.0, “root” account access is disabled.

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.

Brocade Fabric OS before Brocade Fabric OS 9.1.1c, 9.2.0 contains a vulnerability when using various commands such as “chassisdistribute”, “reboot”, “rasman”, errmoduleshow, errfilterset, hassiscfgperrthreshold, supportshowcfgdisable and supportshowcfgenable commands that can cause the content of shell interpreted variables to be printed in the terminal.

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.

A vulnerability in fab_seg.c.h libraries of all Brocade Fabric OS versions before Brocade Fabric OS v9.1.1, v9.0.1e, v8.2.3c, v8.2.0_cbn5, 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”.

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.

A vulnerability in the radius authentication system of Brocade Fabric OS before Brocade Fabric OS 9.0 could allow a remote attacker to execute arbitrary code on the Brocade switch.

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.

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.
