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-2018-0346
 
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.
