CVE-2018-0411: Cisco Unified Communications Manager

Medium severity, CVSS 6.1. EPSS: 1.8% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected software. 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 interface or allow the attacker to access sensitive browser-based information.
