Summary
Karmada PULL Mode Cluster Privilege Escalation
Details

Impact

What kind of vulnerability is it? Who is impacted?

The PULL mode clusters registered with the karmadactl register command have excessive privileges to access control plane resources. By abusing these permissions, an attacker able to authenticate as the karmada-agent to a karmada cluster would be able to obtain administrative privileges over the entire federation system including all registered member clusters.

Patches

Has the problem been patched? What versions should users upgrade to?

Since Karmada v1.12.0, command karmadactl register restricts the access permissions of pull mode member clusters to control plane resources. This way, an attacker able to authenticate as the karmada-agent cannot control other member clusters in Karmada.

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

Restricts the access permissions of pull mode member clusters to control plane resources according to Karmada Component Permissions Docs.
