Summary: CVE-2018-0155 is a vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Catalyst 4500-X Series Switches that lets an unauthenticated, remote attacker crash the iosd process and cause a denial-of-service condition. CISA set a remediation due date of 2022-03-17, and known ransomware campaign use of this CVE is listed as unknown.
What you should know: An unauthenticated remote attacker can take down a switch with no credentials and no local access, and CISA's catalog records no known ransomware use for this CVE - meaning there is no observed exploitation pattern to tell you whether this is being used quietly.
