A vulnerability in the detection engine reassembly of HTTP packets for Cisco Firepower System Software before 6.0.1 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to the Snort process unexpectedly restarting. The vulnerability is due to improper handling of an HTTP packet stream. An attacker could exploit this vulnerability by sending a crafted HTTP packet stream to the detection engine on the targeted device. An exploit could allow the attacker to cause a DoS condition if the Snort process restarts and traffic inspection is bypassed or traffic is dropped.

The Threat Management Console in Cisco Firepower Management Center 5.2.0 through 6.0.1 allows remote authenticated users to execute arbitrary commands via crafted web-application parameters, aka Bug ID CSCva30872.

Cross-site scripting (XSS) vulnerability in Cisco Firepower Management Center 4.10.3, 5.2.0, 5.3.0, 5.3.0.2, 5.3.1, and 5.4.0 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters, aka Bug IDs CSCur25508 and CSCur25518.
