Detailsinfo

A vulnerability classified as problematic has been found in Cisco Firepower System Software (Firewall Software) (unknown version). This affects an unknown code block of the component Snort Detection Engine. The manipulation as part of a Request leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on availability. The summary by CVE is:

A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to restart an instance of the Snort detection engine on an affected device, resulting in a brief denial of service (DoS) condition. The vulnerability is due to the incorrect handling of a Transport Layer Security (TLS) extension during TLS connection setup for the affected software. An attacker could exploit this vulnerability by sending a crafted TLS connection setup request to an affected device. A successful exploit could allow the attacker to cause the Snort detection engine on the affected device to restart, resulting in a DoS condition. Cisco Bug IDs: CSCvg97808.

The bug was discovered 05/02/2018. The weakness was disclosed 05/02/2018 as cisco-sa-20180502-fpwr-txdos as confirmed advisory (Website). The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2018-0281 since 11/27/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation.
