Vulnerability Name:

CVE-2020-3320 (CCN-189513)

Assigned:2019-12-12
Published:2020-10-07
Updated:2020-10-23
Summary:A vulnerability in the web-based management interface of Cisco Firepower Management Center could allow an authenticated, 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 of an affected device. An attacker could exploit this vulnerability by first entering input within the web-based management interface and then persuading a user of the interface to view the crafted input within 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.
