A vulnerability, which was classified as problematic, has been found in Cisco Unified Communications Manager, Unified Communications Manager IM & Presence Service, Unified Communications Manager Session Management Edition and Unity Connection (Unified Communication Software) (unknown version). This issue affects an unknown code of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. Impacted is integrity. An attacker might be able to inject arbitrary html and script code into the web site. This would alter the appearance and would make it possible to initiate further attacks against site visitors. The summary by CVE is:

Multiple vulnerabilities in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an interface user. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by persuading an interface user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

The weakness was released 04/08/2021 as cisco-sa-cucm-xss-Q4PZcNzJ. It is possible to read the advisory at tools.cisco.com. The identification of this vulnerability is CVE-2021-1408 since 11/13/2020.
