Vulnerability from variot
A vulnerability in the data acquisition (DAQ) component of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured access control policies or cause a denial of service (DoS) condition. The vulnerability exists because the affected software improperly manages system memory resources when inspecting traffic. An attacker could exploit this vulnerability by generating specific traffic patterns for the software to inspect. A successful exploit could allow the attacker to exhaust system memory resources used for traffic inspection. Depending on the configuration, the FTD Software could fail open and cease to inspect traffic or fail closed and result in a DoS condition. This vulnerability may require manual intervention to restore the software. Cisco Firepower Threat Defense (FTD) Contains a vulnerability related to failure of the protection mechanism.Service operation interruption (DoS) There is a possibility of being put into a state. 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 CSCvo02577. data acquisition (DAQ) is one of the data acquisition components
