Description

NorthStar C2, prior to commit 7674a44 on March 11 2024, contains a vulnerability where the logs page is
vulnerable to a stored xss.
An unauthenticated user can simulate an agent registration to cause the XSS and take over a users session.
With this access, it is then possible to run a new payload on all of the NorthStar C2 compromised hosts
(agents), and kill the original agent.

Successfully tested against NorthStar C2 commit e7fdce148b6a81516e8aa5e5e037acd082611f73 running on
Ubuntu 22.04. The agent was running on Windows 10 19045.
