Detailsinfo

A vulnerability was found in Cisco ASA and Firepower Threat Defense (Firewall Software) (the affected version unknown). It has been rated as problematic. Affected by this issue is an unknown part of the component OSPF Handler. The manipulation as part of a Packet leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. CVE summarizes:

A vulnerability in the Open Shortest Path First (OSPF) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software improperly parses certain options in OSPF link-state advertisement (LSA) type 11 packets. An attacker could exploit this vulnerability by sending a crafted LSA type 11 OSPF packet to an affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition for client traffic that is traversing the device.

The weakness was presented 10/02/2019 as cisco-sa-20191002-asa-ospf-lsa as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability is handled as CVE-2019-12676 since 06/04/2019. The attack needs to 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.
