An attacker could exploit this vulnerability by invoking the update service command with a crafted argument. An exploit could allow the attacker to run arbitrary commands with SYSTEM user privileges.\r\n\r\n  While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access, administrators should be aware that in Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools.\r\n\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190227-wmda-cmdinj [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190227-wmda-cmdinj\"]",

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:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, 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.\r\n\r\nWhen 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 [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn 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.\r\n  Customers Without Service Contracts\r\nCustomers 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:\r\nhttps://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers 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.\r\n  Fixed Releases\r\nCisco Webex Meetings Desktop App (Cisco Webex Meetings Suite WBS33)\r\n\r\nThis vulnerability is fixed in Cisco Webex Meetings Desktop App Release 33.6.6 and 33.9.1 releases.\r\n\r\nAdministrators can update the Cisco Webex Meetings Desktop App for their user base by following the instructions available in the document IT Administrator Guide for Mass Deployment of the Cisco Webex Meetings Desktop App [\"https://collaborationhelp.cisco.com/article/en-us/nulpixd\"].\r\n\r\n  Users can update the Cisco Webex Meetings Desktop App by launching the Cisco Webex Meetings application and clicking the gear icon in the top right of the application window and then choosing the Check for Updates entry from the drop-down list. This is also documented in the article Update the Cisco Webex Meetings Desktop App [\"https://collaborationhelp.cisco.com/article/en-us/n1kwkd6\"].\r\n\r\nCisco Webex Productivity Tools (Cisco Webex Meetings Suite WBS32)\r\n\r\nThis vulnerability is fixed in Cisco Webex Productivity Tools Release 33.0.7.\r\n\r\nCisco Webex Productivity Tools is an optional companion application that allows users to quickly schedule and join meetings from their desktop without the need to access the Meetings website. The application should not be confused with the Cisco Webex Meetings Client, which is the main client application that provides the core functionality to host or attend a Webex meeting.\r\n\r\nAdministrators can update the Cisco Webex Productivity Tools for their user base by following the instructions available in the document IT Administrator Guide for Mass Deployment of the Cisco Webex Meetings Desktop App [\"https://collaborationhelp.cisco.com/article/en-us/nulpixd\"].\r\n\r\n  Users can update the Cisco Webex Productivity Tools by launching the Cisco Webex Meetings application and clicking Settings in the top right of the application window and then choosing Check for Updates from the drop-down list.
