Detailsinfo

A vulnerability was found in Cisco Firepower 9000 up to 2.1 (Firewall Software) and classified as problematic. Affected by this issue is an unknown functionality of the component Firepower 2-Port 100G Double-Width Network Module. The manipulation as part of a Packet leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is availability. CVE summarizes:

A vulnerability in field-programmable gate array (FPGA) ingress buffer management for the Cisco Firepower 9000 Series with the Cisco Firepower 2-port 100G double-width network module (PID: FPR9K-DNM-2X100G) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. Manual intervention may be required before a device will resume normal operations. The vulnerability is due to a logic error in the FPGA related to the processing of different types of input packets. An attacker could exploit this vulnerability by being on the adjacent subnet and sending a crafted sequence of input packets to a specific interface on an affected device. A successful exploit could allow the attacker to cause a queue wedge condition on the interface. When a wedge occurs, the affected device will stop processing any additional packets that are received on the wedged interface. Version 2.2 is affected.

The bug was discovered 02/20/2019. The weakness was published 02/21/2019 as cisco-sa-20190220-firpwr-dos as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability is handled as CVE-2019-1700 since 12/06/2018. The attack can only be done within the local network. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 2.2 eliminates this vulnerability.
