Cross-task secret disclosure via missing process namespaces
Published Feb 1, 2021 · Updated Aug 3, 2024
Information disclosure in HashiCorp Nomad and Nomad Enterprise allows attackers to read secrets from other tasks on the same node. The Linux exec and java task drivers launch workloads without separate PID and IPC namespaces, exposing same-user process command lines, environments, and filesystems. Exploitation requires a malicious task to run through an affected driver on the same client node; the reported consequence is limited to cross-task confidentiality loss.
