Cisco NX-OS Software Cisco Fabric Services Over IP Denial of Service Vulnerability

cisco-sa-cfsoip-dos-tpykyDr · High · Published · Updated

A vulnerability in the Cisco Fabric Services over IP (CFSoIP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of incoming CFSoIP packets. An attacker could exploit this vulnerability by sending crafted CFSoIP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link:https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cfsoip-dos-tpykyDr This advisory is part of the February 2022 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication.
