CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N/E:X/RL:X/RC:X
-
A vulnerability in the web-based interface of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition (SME), Cisco Unified Communications Manager IM and Presence (Unified CM IM&P) Service, and Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.
The vulnerability is due to insufficient CSRF protections by the affected software. An attacker could exploit this vulnerability by persuading a targeted user to click a malicious link. A successful exploit could allow the attacker to send arbitrary requests that could change the password of a targeted user. An attacker could then take unauthorized actions on behalf of the targeted user.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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.htmlAdditionally, 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.htmlCustomers 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.
