What is CVE-2020-3466?
CVE-2020-3466 is a medium-severity cross-site scripting vulnerability in Cisco Digital Network Architecture Center (DNA Center), published on 26 Aug 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Multiple vulnerabilities in the web-based management interface of Cisco DNA Center software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device. The vulnerabilities exist because the web-based management interface on an affected device does not properly validate user-supplied input. An attacker could exploit these vulnerabilities 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 affected interface or access sensitive, browser-based information.
