CVE-2018-0124
CWE-320

Summary

  * A vulnerability in Cisco Unified Communications Domain Manager could allow
    an unauthenticated, remote attacker to bypass security protections, gain
    elevated privileges, and execute arbitrary code.

    The vulnerability is due to insecure key generation during application
    configuration. An attacker could exploit this vulnerability by using a
    known insecure key value to bypass security protections by sending
    arbitrary requests using the insecure key to a targeted application. An
    exploit could allow the attacker to execute arbitrary code.

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

Affected Products

  * Vulnerable Products

    This vulnerability affects Cisco Unified Communications Domain Manager
    releases prior to 11.5(2), including Cisco Unified Communications Domain
    Manager Classic releases 8.1.9 and prior.

    To determine which release of the software is currently running on a
    device, administrators may use the app status command in the device CLI.
    The output of the command in the CLI is similar to the following example:

    Products Confirmed Not Vulnerable

    No other Cisco products are currently known to be affected by this
    vulnerability.

Workarounds

  * There are no workarounds that address this vulnerability.

Fixed Software

  * 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

    The vulnerability is fixed in Cisco Unified Communications Domain Manager
    releases 11.5(2) and later.

    The software can be downloaded from the Software Center on Cisco.com by
    navigating to Products > Unified Communications > Call Control > Hosted
    Collaboration > Hosted Collaboration Solution (HCS) > Hosted Collaboration
    Solution Version 11.5 > Unified Communications Domain Manager (CUCDM)
    Updates-11.5(2).

    A patch for Cisco Unified Communications Domain Manager Classic release 8.1
    (9) ER1 can be downloaded from the Software Center on Cisco.com by
    navigating to Products > Unified Communications > Call Control > Hosted
    Collaboration > Hosted Collaboration Solution (HCS) > Hosted Collaboration
    Solution Version 11.5 > Unified Communications Domain Manager (CUCDM)
    Updates-8.1.9ER1.

Cisco Security Advisory

Cisco Unified Communications Manager Reflected Cross-Site Scripting
Vulnerability

Medium


Advisory ID: cisco-sa-20180221-ucm

First Published: 2018 February 21 16:00 GMT

Version 1.0: Final

Workarounds: No workarounds available

Cisco Bug IDs: CSCvg74815

CVE-2018-0206

CWE-79

CVSS Score: Base 6.1

CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X


Summary

  o A vulnerability in the web-based management interface of Cisco Unified
    Communications Manager could allow an unauthenticated, remote attacker to
    conduct a reflected cross-site scripting (XSS) attack against a user of the
    web-based management interface of an affected device.

    The vulnerability is due to insufficient validation of user-supplied input
    by the web-based management interface of an affected device. An attacker
    could exploit this vulnerability by persuading a user of the web-based
    management interface to click a link that submits malicious input to the
    interface. A successful exploit could allow the attacker to execute
    arbitrary script code in the context of the interface or allow the attacker
    to access sensitive browser-based information.

    There are no workarounds that address this vulnerability.
