Cisco Smart Software Manager On-Prem Static Default Credential Vulnerability

Priority:        Critical

Advisory ID:     cisco-sa-on-prem-static-cred-sL8rDs8

Workarounds:     No workarounds availableCisco Bug IDs:   CSCvs42156



CVSS Score:


  o A vulnerability in the High Availability (HA) service of Cisco Smart
    Software Manager On-Prem could allow an unauthenticated, remote attacker to
    access a sensitive part of the system with a high-privileged account.

    The vulnerability is due to a system account that has a default and static
    password and is not under the control of the system administrator. An
    attacker could exploit this vulnerability by using this default account to
    connect to the affected system. A successful exploit could allow the
    attacker to obtain read and write access to system data, including the
    configuration of an affected device. The attacker would gain access to a
    sensitive portion of the system, but the attacker would not have full
    administrative rights to control the device.

    Cisco has released software updates that address the vulnerability
    described in this advisory. There are no workarounds that address this

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco Smart Software Manager On-Prem releases
    earlier than 7-202001 if the High Availability (HA) feature is enabled. HA
    is not enabled by default.

    Determine Whether High Availability Is Enabled

    The HA feature must be enabled for Cisco Smart Software Manager On-Prem to
    be affected by the vulnerability described in this advisory. To determine
    whether the HA feature is configured on a device, administrators can log in
    to the administrative web interface and look for the presence of the High
    Availability Status widget in the main dashboard. If the widget exists, HA
    is enabled. Administrators can also SSH to the system, enter onprem-console
    at the prompt, and issue the ha_status command at the CLI.

    The following example shows the CLI output when HA is enabled:

        [admin@SSM-On-Prem ~]$ onprem-console
        SSM On-Prem Console
        >> ha_status

    Products Confirmed Not Vulnerable

    Only products listed in the Vulnerable Products section of this advisory
    are known to be affected by this vulnerability.


  o Cisco Smart Software Manager satellite and Cisco Smart Software Manager
    On-Prem are the same product. Prior to Release 7.0, this product was named
    Cisco Smart Software Manager satellite. As of Release 7.0, this product has
    been named Cisco Smart Software Manager On-Prem (SSM On-Prem).


  o There are no workarounds that address this vulnerability.

Fixed Software

  o Cisco has released free software updates that address the vulnerability
    described in this advisory. Customers may only install and expect support
    for software versions and feature sets for which they have purchased a
    license. By installing, downloading, accessing, or otherwise using such
    software upgrades, customers agree to follow the terms of the Cisco
    software license: https://www.cisco.com/c/en/us/products/

    Additionally, customers may only download software for which they have a
    valid license, procured from Cisco directly, or through a Cisco authorized
    reseller or partner. In most cases this will be a maintenance upgrade to
    software that was previously purchased. Free security software updates do
    not entitle customers to a new software license, additional software
    feature sets, or major revision upgrades.

    When considering software upgrades , customers are advised to regularly
    consult the advisories for Cisco products, which are available from the
    Cisco Security Advisories and Alerts page , to determine exposure and a
    complete upgrade solution.

    In all cases, customers should ensure that the devices to be upgraded
    contain sufficient memory and confirm that current hardware and software
    configurations will continue to be supported properly by the new release.
    If the information is not clear, customers are advised to contact the Cisco
    Technical Assistance Center (TAC) or their contracted maintenance

    Customers Without Service Contracts

    Customers who purchase directly from Cisco but do not hold a Cisco service
    contract and customers who make purchases through third-party vendors but
    are unsuccessful in obtaining fixed software through their point of sale
    should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c

    Customers should have the product serial number available and be prepared
    to provide the URL of this advisory as evidence of entitlement to a free

    Fixed Releases

    Cisco fixed this vulnerability in Cisco Smart Software Manager On-Prem
    releases 7-202001 and later.
