Name of the Vulnerable Software and Affected Versions: Cisco Firepower System Software (affected versions not specified)

Description: A flaw in the detection engine could allow an unauthenticated, remote attacker to bypass configured file action policies if an Intelligent Application Bypass (IAB) with a drop percentage threshold is also configured. This is due to incorrect counting of the percentage of dropped traffic. An attacker could exploit this by sending network traffic to a targeted device, potentially allowing traffic that should be dropped into the network.
