A vulnerability, which was classified as problematic, was found in Cisco Unified Communications Manager, Unified Communications Manager IM & Presence Service, Unified Communications Manager Session Management Edition and Unity Connection (Unified Communication Software) (version unknown). Affected is an unknown code block of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. This is going to have an impact on 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. CVE summarizes:

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 disclosed 04/08/2021 as cisco-sa-cucm-xss-Q4PZcNzJ. The advisory is shared for download at tools.cisco.com. This vulnerability is traded as CVE-2021-1409 since 11/13/2020. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/11/2021). The MITRE ATT&CK project declares the attack technique as T1059.007.
