Detailsinfo

A vulnerability classified as problematic was found in Cisco IOS and IOS XE (Router Operating System) (affected version not known). This vulnerability affects some unknown functionality of the component Cluster Management Protocol Handler. The manipulation as part of a Packet leads to a input validation vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. CVE summarizes:

A vulnerability in the Cluster Management Protocol (CMP) processing code in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation when processing CMP management packets. An attacker could exploit this vulnerability by sending malicious CMP management packets to an affected device. A successful exploit could cause the switch to crash, resulting in a DoS condition. The switch will reload automatically.

The bug was discovered 03/27/2019. The weakness was released 03/28/2019 as cisco-sa-20190327-cmp-dos as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability was named CVE-2019-1746 since 12/06/2018. The attack can only be initiated within the local network. No form of authentication is required for a successful exploitation.
