Medium severity, CVSS 4.8. EPSS: 0.9% chance of exploitation in the next 30 days.

A vulnerability in the web-based interface of Cisco Unity Connection could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based interface of the affected software. The vulnerability is due to insufficient validation of user-supplied input that is processed by the web-based interface of the affected software.
