Cilium Tetragon unauthenticated admin API exposed to hostNetwork pods

A container security tool can be reached without a lock, letting attackers take control.

Summary

Tetragon's gRPC admin API is reachable without authentication over a TCP listener, so an attacker running or controlling hostNetwork pods on the same node can escalate privileges or escape a container. Versions before 1.7.0 are affected, and the Helm default causes it.

Affected when

  • Helm default install exposing an unauthenticated TCP listener
  • attacker can run or compromise hostNetwork pods on the same node

What to do

Update to version 1.7.0 or later. The sources give no stopgap.

Products and platforms

  • Linux
  • Cilium Tetragon
