CVE-2024-3177: Bypassing mountable secrets policy imposed by the ServiceAccount admission plugin

Noroxi assessment

Priority: Monitor (action score 11/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.2% (FIRST EPSS); higher than 82.7% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: kubernetes (Debian:12) 1.20.5+really1.20.2-1; k8s.io/kubernetes (Go) 1.28.9, 1.29.4, 1.27.13; kubernetes1.23 (openSUSE:Leap 15.5) 1.23.17-150500.3.12.1.

Low priority for now. Upgrade to kubernetes (Debian:12) 1.20.5+really1.20.2-1; k8s.io/kubernetes (Go) 1.28.9, 1.29.4, 1.27.13; kubernetes1.23 (openSUSE:Leap 15.5) 1.23.17-150500.3.12.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A security issue was discovered in Kubernetes where users may be able to launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using containers, init containers, and ephemeral containers with the envFrom field populated. The policy ensures pods running with a service account may only reference secrets specified in the service account’s secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the kubernetes.io/enforce-mountable-secrets annotation are used together with containers, init containers, and ephemeral containers with the envFrom field populated.
