CVE-2018-0349
CWE-20
Summary
A vulnerability in the Cisco SD-WAN Solution could allow an authenticated,
remote attacker to overwrite arbitrary files on the underlying operating
system of an affected device.
The vulnerability is due to improper input validation of the request
admin-tech command in the CLI of the affected software. An attacker could
exploit this vulnerability by modifying the request admin-tech command in
the CLI of an affected device. A successful exploit could allow the
attacker to overwrite arbitrary files on the underlying operating system of
an affected device and escalate their privileges to the root user.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

CVE-2018-0345
CWE-20
Summary
A vulnerability in the configuration and management database of the Cisco
SD-WAN Solution could allow an authenticated, remote attacker to execute
arbitrary commands with the privileges of the vmanage user in the
configuration management system of the affected software.
The vulnerability is due to insufficient validation of command arguments
that are passed to the configuration and management database of the
affected software. An attacker could exploit this vulnerability by creating
custom functions that contain malicious code and are executed as the
vmanage user of the configuration management system. A successful exploit
could allow the attacker to execute arbitrary commands with the privileges
of the vmanage user in the configuration management system of the affected
software.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

CVE-2018-0342
CWE-119
Summary
o A vulnerability in the configuration and monitoring service of the
Cisco SD-WAN Solution could allow an authenticated, local attacker to
execute arbitrary code with root privileges or cause a denial of service
(DoS) condition on an affected device.
The vulnerability is due to incomplete bounds checks for data that is
provided by the configuration and monitoring service of the affected
solution. An attacker could exploit this vulnerability by sending malicious
data to the vDaemon listening service on an affected device. A successful
exploit could allow the attacker to cause a buffer overflow condition on
the affected device, which could allow the attacker to execute arbitrary
code with root privileges on the device or cause the vDaemon listening
service to reload and result in a DoS condition on the device.
There are no workarounds that address this vulnerability.

CVE-2018-0346
CWE-119
Summary
o A vulnerability in the Zero Touch Provisioning service of the Cisco SD-WAN
Solution could allow an unauthenticated, remote attacker to cause a denial
of service (DoS) condition on an affected device.
The vulnerability is due to incorrect bounds checks for certain values in
packets that are sent to the Zero Touch Provisioning service of the
affected software. An attacker could exploit this vulnerability by sending
malicious packets to the affected software for processing. When the
software processes the packets, a buffer overflow condition could occur and
cause an affected device to reload. A successful exploit could allow the
attacker to cause a temporary DoS condition while the device reloads.
This vulnerability can be exploited only by traffic that is destined for an
affected device. It cannot be exploited by traffic that is transiting a
device.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
