CVE-2024-20310 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. A vulnerability in the web-based interface of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an authenticated user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to click a crafted link. EPSS estimates a 0.50% chance of exploitation in the next 30 days.

Description

A vulnerability in the web-based interface of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an authenticated user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading an authenticated user of the interface 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.
