CWE-798

Summary

  * A vulnerability in Cisco Umbrella Insights Virtual Appliances could allow
    an authenticated, local attacker to log in to an affected virtual appliance
    with root privileges.

    The vulnerability is due to the presence of default, static user
    credentials for an affected virtual appliance. An attacker could exploit
    this vulnerability by using the hypervisor console to connect locally to an
    affected system and then using the static credentials to log in to an
    affected virtual appliance. A successful exploit could allow the attacker
    to log in to the affected appliance with root privileges.

    There are no workarounds that address this vulnerability.
