Vulnerability from variot
A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker 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 attacker to bypass configured IPS rules and allow uninspected traffic onto the network. Cisco Firepower System The software is vulnerable to resource exhaustion.Information may be tampered with. Remote attackers can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is being tracked by Cisco Bug IDs CSCvk76547
