Affected Products

  o Vulnerable Products

    These vulnerabilities affect Cisco devices if they are running a vulnerable
    release of Cisco SD-WAN vManage Software.

    For a device to be affected by CVE-2021-1302, the Multi-Tenant feature must
    be enabled.

    For information about which Cisco software releases are vulnerable, see the
    Fixed Software section of this advisory.

    Products Confirmed Not Vulnerable

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

    Cisco has confirmed that these vulnerabilities do not affect the following
    products:

       IOS XE SD-WAN Software
       SD-WAN vBond Orchestrator Software
       SD-WAN vEdge Cloud Routers
       SD-WAN vEdge Routers
       SD-WAN vSmart Controller Software

Details

  o The vulnerabilities are not dependent on one another; exploitation of one
    of the vulnerabilities is not required to exploit another vulnerability. In
    addition, a software release that is affected by one of the vulnerabilities
    may not be affected by the other vulnerabilities.

    Details about the vulnerabilities are as follows:

    CVE-2021-1302: Cisco SD-WAN vManage Authorization Bypass Vulnerability

    A vulnerability in the web-based management interface of Cisco SD-WAN
    vManage Software could allow an authenticated, remote attacker to bypass
    authorization and connect to other vManage tenants that they are not
    authorized to connect to.

    The vulnerability is due to insufficient authorization checks. An attacker
    could exploit this vulnerability by sending crafted HTTP requests to the
    web-based management interface of an affected system. A successful exploit
    could allow the attacker to bypass authorization and connect to other
    vManage tenants that they are not authorized to connect to.

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

    Bug ID(s): CSCvu28377
    CVE ID: CVE-2021-1302
    Security Impact Rating (SIR): High
    CVSS Base Score: 8.8
    CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

    CVE-2021-1304: Cisco SD-WAN vManage Authorization Bypass Vulnerability

    A vulnerability in the web-based management interface SSH console of Cisco
    SD-WAN vManage Software could allow an authenticated, remote attacker to
    access sensitive information that they are not normally authorized to
    access.

    The vulnerability is due to insufficient authorization checks. An attacker
    could exploit this vulnerability by logging in to the web-based management
    interface and using the SSH console feature. A successful exploit could
    allow the attacker to access sensitive information, which would allow them
    to carry out further attacks.

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

    Bug ID(s): CSCvs11283
    CVE ID: CVE-2021-1304
    Security Impact Rating (SIR): Medium
    CVSS Base Score: 4.3
    CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

    CVE-2021-1305: Cisco SD-WAN vManage Authorization Bypass Vulnerability

    A vulnerability in the web-based management interface of Cisco SD-WAN
    vManage Software could allow an authenticated, remote attacker to access
    information such as logs, configurations, and device information that they
    are not authorized to view.

    The vulnerability is due to insufficient authorization checks of user
    account privileges. An attacker could exploit this vulnerability by logging
    in to the web-based management interface with a low-privileged user
    account. A successful exploit could allow the attacker to access sensitive
    information that they are not authorized to view.

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

    Bug ID(s): CSCvi59734
    CVE ID: CVE-2021-1305
    Security Impact Rating (SIR): Medium
    CVSS Base Score: 4.3
    CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

Workarounds

  o There are no workarounds that address these vulnerabilities.

Fixed Software

  o Cisco has released free software updates that address the vulnerabilities
    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 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

    Customers are advised to upgrade to an appropriate fixed software release
    as indicated in the following table(s). To ensure a complete upgrade
    solution, consider that this advisory is part of a collection that includes
    the following advisories:

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

Summary

  o Multiple vulnerabilities in the web-based management interface of Cisco
    SD-WAN vManage Software could allow an unauthenticated, remote attacker to
    conduct SQL injection attacks on an affected system.
