The vulnerability is due to insufficient validation of user-supplied input to the xAPI of the affected software. An attacker could exploit this vulnerability by sending a crafted request to the xAPI. A successful exploit could allow the attacker to read and write arbitrary files in the system. To exploit this vulnerability, an attacker would need either an In-Room Control or administrator account. Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ cisco-sa-telepresence-path-tr-wdrnYEZZ [/CVE-2020-3143_su] Affected Products o [CVE-2020-3143_ap] [/CVE-2020-3143_ap] Vulnerable Products [CVE-2020-3143_vp] This vulnerability affects the following Cisco products if they are running a vulnerable release of Cisco TelePresence CE Software, Cisco TC Software, or Cisco RoomOS Software: Cisco TelePresence Integrator C Series Cisco TelePresence MX Series Cisco TelePresence SX Series Cisco TelePresence System EX Series Cisco Webex Board Cisco Webex DX Series Cisco Webex Room Series For information about which Cisco software releases are vulnerable, see the Fixed Software section of this advisory. [/CVE-2020-3143_vp] Products Confirmed Not Vulnerable [CVE-2020-3143_nv] Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability. [/CVE-2020-3143_nv] Workarounds o [CVE-2020-3143_wa] There are no workarounds that address this vulnerability. [/CVE-2020-3143_wa] Fixed Software o [CVE-2020-3143_fs] 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.
