CVE-2018-15434: Cisco skinny client control protocol software cross-site scripting vulnerability

Cisco · Skinny Client Control Protocol Software

A vulnerability in the web-based management interface of Cisco Unified IP Phone 7900 Series 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. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious 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.
