Broadcom Brocade Fabric OS contains a code injection vulnerability that allows a local user with administrative privileges to execute arbitrary code with full root privileges.

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 memory leak in the fastrpcdmabufattach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dmagetsgtable() failures, aka CID-fc739a058d99.

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vividstopgeneratingvidcap(), vividstopgeneratingvidout(), sdrcapstopstreaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

A fundamental design flaw within the RADIUS protocol has been proven to be exploitable, compromising the integrity in the RADIUS Access-Request process. The attack allows a malicious user to modify packets in a way that would be indistinguishable to a RADIUS client or server. To be successful, the attacker must have the ability to inject themselves between the client and server.

A Vulnerability in the configdownload command of Brocade Fabric OS command line interface (CLI) versions before 8.2.1, 8.1.2f, 8.0.2f, 7.4.2d could allow a local attacker to escape the restricted shell and, gain root access.

A vulnerability in Brocade Fabric OS versions before 9.2.1c2 could allow an administrator-level user to execute the bind command, to escalate privileges and bypass security controls allowing the execution of arbitrary commands.

A vulnerability in the secure configuration of authentication and management services in Brocade Fabric OS before Fabric OS 9.2.1c2 could allow an authenticated, remote attacker with administrative credentials to execute arbitrary commands as root using “supportsave”, “seccertmgmt”, “configupload” command.

A vulnerability in Brocade Fabric OS could allow an authenticated, local attacker with privileges to access the Bash shell to access insecurely stored file contents including the history command.

A vulnerability in Brocade Fabric OS before 9.2.1c3 could allow elevating the privileges of the local authenticated user to “root” using the export option of seccertmgmt and seccryptocfg commands.

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.

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.

A segmentation fault can occur in Brocade Fabric OS after Brocade Fabric OS v9.0 and before Brocade Fabric OS v9.2.0a through the passwdcfg command. This could allow an authenticated privileged user local user to crash a Brocade Fabric OS swith using the cli “passwdcfg --set -expire -minDiff“.

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 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.

A locking issue was discovered in the tty subsystem of the Linux kernel in drivers/tty/ttyjobctrl.c which could allow an attacker with a local account to possibly corrupt memory or escalate privileges.

A vulnerability in Brocade Fabric OS before 9.2.1c2 could allow an authenticated attacker with admin privileges using the shell commands “source, ping6, sleep, disown, wait to modify the path variables and move upwards in the directory structure or to traverse to different directories.

A vulnerability in Brocade Fabric OS before 9.2.1 could allow an authenticated attacker with admin privileges using the shell command “grep” to modify the path variables and move upwards in the directory structure or to traverse to different directories.

Brocade Fabric OS before 9.2.1 has a vulnerability that could allow a local authenticated attacker to reveal command line passwords using commands that may expose higher privilege sensitive information by a lower privileged user.

A path transversal vulnerability in Brocade Fabric OS 9.1.0 through 9.2.2 could allow a local admin user to gain access to files outside the intended directory potentially leading to the disclosure of sensitive information.

Note: Admin level privilege is required on the switch in order to exploit

A vulnerability in Brocade Fabric OS software v9.1.1, v9.0.1e, v8.2.3c, v7.4.2j, and earlier versions could allow a remote unauthenticated attacker to execute on a Brocade Fabric OS switch commands capable of modifying zoning, disabling the switch, disabling ports, and modifying the switch IP address.

curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.

DISPUTED scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."

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.

GNU glibc is vulnerable to a denial of service, caused by a buffer over-read in iconv feature. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a SIGSEGV.

A flaw was found in the way libcurl handled TLS 1.3 session tickets. A malicious HTTPS proxy could possibly use this flaw to make libcurl resume a TLS session it previously had with the proxy while intending to resume a TLS session with a target server, making it possible for the proxy to perform a man-in-the-middle attack.

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 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”.
