This vulnerability in the Web UI feature of Cisco IOS XE Software allows a remote, unauthenticated threat actor to create an account on a vulnerable system with privilege level 15 access. The threat actor could then potentially use that account to gain control of the affected system.

This plugin only works with Tenable.ot.
