CVE-2021-1409 Information

Description

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.
