cisco-sa-fmc-xss-yT8LNSeA: Cisco Firepower Management Center Software Cross-Site Scripting Vulnerabilities
First published: Wed Apr 28 2021(Updated: )
Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. 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 interface or access sensitive, browser-based information. Cisco has released software updates to address these vulnerabilities. There are no workarounds that address these vulnerabilities.
