"A vulnerability in the web UI of Cisco FXOS and Cisco UCS Fabric
Interconnect Software could allow an unauthenticated, remote attacker
to cause a buffer overflow on an affected system. The vulnerability is
due to incorrect input validation in the web UI. An attacker could
exploit this vulnerability by sending a malicious HTTP or HTTPS packet
directed to the physical management interface of an affected system. A
successful exploit could allow the attacker to cause the process to
crash and possibly reload the device, resulting in a denial of service
(DoS) condition on the affected system. This vulnerability affects
Firepower 4100 Series Next-Generation Firewall, Firepower 9300
Security Appliance, UCS 6200 Series Fabric Interconnects, UCS 6300
Series Fabric Interconnects. Cisco Bug IDs: CSCvb61398, CSCvb86799.
