Description

Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. To exploit these vulnerabilities, the attacker must have valid device credentials, but does not need Administrator privileges. These vulnerabilities are due to insufficient validation of user-supplied input for certain configuration options. An attacker could exploit these vulnerabilities by using crafted input within the device configuration GUI. A successful exploit could allow the attacker to execute arbitrary commands on the device, including on the underlying operating system, which could also affect the availability of the device.
