CVE-2020-3491

MediumCVSS 4.8/10Last modified Jun 17, 2026

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.
