Implementation of the Simple Network
Management Protocol (SNMP) operating on the Brocade 6547 (FC5022)
embedded switch blade, makes internal script calls to system.sh from
within the SNMP binary. An authenticated attacker could perform command
or parameter injection on SNMP operations that are only enabled on the
Brocade 6547 (FC5022) embedded switch. This injection could allow the
authenticated attacker to issue commands as Root.
If Brocade Fabric OS before Fabric OS 9.2.0 configuration settings are not set to encrypt SNMP passwords, then the SNMP privsecret / authsecret fields can be exposed in plaintext. The plaintext passwords can be exposed in a configupload capture or a supportsave capture if encryption of passwords is not enabled. An attacker can use these passwords to fetch values of the supported OIDs via SNMPv3 queries. There are also a limited number of MIB objects that can be modified.
A command injection vulnerability in Brocade Fabric OS before 9.2.0c, and 9.2.1 through 9.2.1a on IP extension platforms could allow a local authenticated attacker to perform a privileged escalation via crafted use of the portcfg command.
This specific exploitation is only possible on IP Extension platforms: Brocade 7810, Brocade 7840, Brocade 7850 and on Brocade X6 or X7 directors with an SX-6 Extension blade installed. The attacker must be logged into the switch via SSH or serial console to conduct the attack.
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.
