CVE-2020-3354: Cisco data center network manager cross-site scripting vulnerability
Cisco · Data Center Network Manager
A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker with administrative credentials to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability is due to insufficient input validation by the web-based management interface. 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 affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker would need administrative credentials on the affected device.
