A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote malicious user to bypass a configured Intrusion Prevention System (IPS) rule that inspects certain types of TCP traffic. The vulnerability is due to incorrect TCP retransmission handling. An attacker could exploit this vulnerability by sending a crafted TCP connection request through an affected device. A successful exploit could allow the malicious user to bypass configured IPS rules and allow uninspected traffic onto the network.
