Summary

Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected device. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities by inserting crafted input into various data fields in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface, or access sensitive, browser-based information. In some cases, it is also possible to cause a temporary availability impact to portions of the FMC Dashboard.
