MEDIUMCisco Secure Firewall Management Center - Unauthenticated Denial of Service via TLS TCP Connection Handling
Title source: llmDescription
A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to restart an instance of the Snort detection engine on an affected device, resulting in a brief denial of service (DoS) condition. The vulnerability is due to the incorrect handling of Transport Layer Security (TLS) TCP connection setup for the affected software. An attacker could exploit this vulnerability by sending crafted TLS traffic to an affected device. A successful exploit could allow the attacker to cause the Snort detection engine on the affected device to restart, resulting in a DoS condition. Cisco Bug IDs: CSCvg99327.
