 Summary
 
A vulnerability in Cisco NX-OS System Software could allow an
authenticated, local attacker to bypass signature verification when
loading a software patch.
The vulnerability is due to insufficient NX-OS signature verification
for software patches. An authenticated, local attacker could exploit
this vulnerability to bypass signature verification and load a
crafted, unsigned software patch on a targeted device. The attacker
would need valid administrator credentials to perform this exploit.
There are no workarounds that address this vulnerability.

 Summary
 
A vulnerability in the CLI of Cisco NX-OS System Software could allow
an authenticated, local attacker to perform a command injection
attack.
The vulnerability is due to insufficient input validation of command
arguments. An attacker could exploit this vulnerability by injecting
crafted command arguments into a vulnerable CLI command and gain
unauthorized access to the underlying operating system of the device.
An exploit could allow the attacker to execute arbitrary commands at
the users privilege level. On products that support multiple virtual
device contexts (VDCs), this vulnerability could allow an attacker to
execute commands at the users privilege level outside the users
environment.
There are no workarounds that address this vulnerability.

 Summary
 
A vulnerability in the TCL scripting subsystem of Cisco NX-OS System
Software could allow an authenticated, local attacker to escape the
interactive TCL shell and gain unauthorized access to the underlying
operating system of the device.
The vulnerability exists due to insufficient input validation of user-
supplied files passed to the interactive TCL shell of the affected
device. An attacker could exploit this vulnerability to escape the
scripting sandbox and execute arbitrary commands on the underlying
operating system with the privileges of the authenticated user.
To exploit this vulnerability, an attacker must have local access and
be authenticated to the targeted device with administrative or tclsh
execution privileges.
There are no workarounds that address this vulnerability.

 Summary
 
A vulnerability in the CLI of Cisco NX-OS System Software could allow
an authenticated, local attacker to read the contents of arbitrary
files.
The vulnerability is due to insufficient input validation for a
specific CLI command. An attacker could exploit this vulnerability by
issuing a crafted command on the CLI. An exploit could allow the
attacker unauthorized access to read arbitrary files on the underlying
local file system. On products that support multiple virtual device
contexts (VDCs), this vulnerability could allow an attacker to read
files from any VDC.
There are no workarounds that address this vulnerability.

 Summary
 
A vulnerability in the CLI of Cisco NX-OS System Software could allow
an authenticated, local attacker to perform a command injection
attack.
The vulnerability is due to insufficient input validation of command
arguments to the CLI parser. An attacker could exploit this
vulnerability by injecting crafted command arguments into a vulnerable
CLI command. An exploit could allow the attacker to execute arbitrary
commands at the user's privilege level. On products that support
multiple virtual device contexts (VDCs), this vulnerability could
allow the attacker to execute commands at the user's privilege level
outside the user's environment.
There are no workarounds that address this vulnerability.

 Summary
 
A vulnerability in the CLI of Cisco NX-OS System Software could allow
an authenticated, local attacker to perform a command injection
attack. An attacker would need valid administrator credentials to
perform this exploit.
The vulnerability is due to insufficient input validation during the

 Summary
 
A vulnerability in the Open Agent Container (OAC) feature of Cisco
Nexus Series Switches could allow an unauthenticated, local attacker
to read and send packets outside the scope of the OAC.
The vulnerability is due to insufficient internal security measures in
the OAC feature. An attacker could exploit this vulnerability by
crafting specific packets for communication on the device-internal
network. A successful exploit could allow the attacker to run code on
the underlying host operating system.
OAC is not enabled by default. For a device to be vulnerable, an
administrator would need to install and activate this feature.
There are no workarounds that address this vulnerability.
