Title
Cluster-curator-controller: cluster-curator-controller: spec.install.overridejob allows arbitrary job spec injection
Summary
A flaw was found in the cluster-curator-controller component of multicluster engine (MCE). A tenant with create or update permissions on ClusterCurator resources can inject an arbitrary Job specification. This is possible because the CreateJob() function does not validate user-controlled input when unmarshaling the spec.install.overrideJob raw extension. Successful exploitation allows the injected Job to run with the controller's elevated privileges, leading to arbitrary code execution and privilege escalation, potentially accessing cluster-wide secrets.

A tenant with create or update permissions on ClusterCurator resources can inject an arbitrary Job specification.

Successful exploitation allows the injected Job to run with the controller\u0027s elevated privileges, leading to arbitrary code execution and privilege escalation, potentially accessing cluster-wide secrets."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
