CVE-2017-12356: Cisco Jabber

Medium severity, CVSS 6.1. EPSS: 1.2% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Jabber for Windows, Mac, Android, and iOS could allow an unauthenticated, remote attacker to conduct a 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 an affected device. 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.
