CVE-2020-3491 Information

Description

A vulnerability in the web-based management interface of Cisco Vision Dynamic Signage Director could allow an authenticated remote attacker with administrative privileges to conduct a cross-site scripting (XSS) attack against a user of the interface on an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive browser-based information. To exploit this vulnerability the attacker would need to have administrative privileges on the affected device.
