CVSS Score:
8.2  AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H/E:X/RL:X/RC:X

Summary

  o A vulnerability in the application programming interface (API) of Cisco
    Smart Software Manager On-Prem could allow an unauthenticated, remote
    attacker to change user account information which can prevent users from
    logging in, resulting in a denial of service (DoS) condition of the web
    interface.

    The vulnerability is due to the lack of input validation in the API. An
    attacker could exploit this vulnerability by sending a crafted HTTP request
    to an affected device. An exploit could allow the attacker to change or
    corrupt user account information which could grant the attacker
    administrator access or prevent legitimate user access to the web
    interface, resulting in a denial of service (DoS) condition.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco Smart Software Manager On-Prem releases
    earlier than 7-201910.

    Note : 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 is named Cisco Smart Software Manager On-Prem (SSM On-Prem).

    Products Confirmed Not Vulnerable

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

Workarounds

  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/end-user-license-agreement.html

    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
    providers.

    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/en/us/support/web/tsd-cisco-worldwide-contacts.html

    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
    upgrade.

    Fixed Releases

    Cisco fixed this vulnerability in Cisco Smart Software Manager On-Prem
    Release 7-201910 and later.

  o The Cisco Product Security Incident Response Team (PSIRT) is not aware of
    any public announcements or malicious use of the vulnerability that is
    described in this advisory.
