The vulnerability affects the web interface for managing the Cisco Integrated Management Controller (IMC) Supervisor, as well as tools for managing physical infrastructure and IaaS virtual environments like Cisco UCS Director and Cisco UCS Director Express for Big Data. This allows a malicious actor to trigger a service failure.

Lack of authentication in Cisco IMC Supervisor APIs enables service interruptions.
