CVE-2024-31990: Argo CD's API server does not enforce project sourceNamespaces
I can convince the UI to let me do things with an invalid Application.
- Admin gives me
p, michael, applications, *, demo/*, allow, wheredemocan just deploy to thedemonamespace - Admin gives me AppProject
devwhich reconciles from nsdev-apps - Admin gives me
p, michael, applications, sync, dev/*, allow, i.e. no updating via the UI allowed, gitops-only - I create an Application called
pwnindev-appswith project dev and sync the app with sources from git - I change the Application’s project to demo via kubectl or gitops (whichever mechanism my admins have given me, because it should be safe)
- I use the UI to edit the resource which should only be mutable via gitops
