This vulnerability has a CVSS 3.1 base score of 3.8, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

A user authenticating to Kubernetes clusters via the Pinniped Supervisor could potentially gain elevated permissions in the clusters, only if all the following conditions were true: the Pinniped Supervisor server is running with an ActiveDirectoryIdentityProvider resource configured; the ActiveDirectoryIdentityProvider.spec.groupSearch.attributes.groupName is empty; the attacker gains the ability to edit some part of the distinguished name (DN) of group entries in the Active Directory (AD) server's database for groups to which they belong; the configured group search parameters cause the edited group to be included in the group search results for the user; and the attacker knows the password for an AD user who belongs to the edited AD group.

Affected versions: Pinniped (go.pinniped.dev) v0.11.0 through v0.46.0 inclusive; fixed in v0.47.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
