CVE-2024-20305: Cisco Unity Connection

Medium severity, CVSS 4.8. EPSS: 0.4% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Unity Connection could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a 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 a 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.
