Vulnerability from fkie_nvd - Published: 2020-10-08 05:15 - Updated: 2026-06-17 03:17
Severity
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
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.
