CVE-2026-47828 – Missing TLS Certificate Verification in BOSH CLI Allows Root Code Execution via Man-in-the-Middle Credential Replay

CVE ID :CVE-2026-47828

Published : July 9, 2026, 7:16 a.m. | 32 minutes ago

Description :During bosh create-env and bosh delete-env, the CLI uploads compiled CPI packages and rendered job templates to the new VM’s DAV blobstore over HTTPS without verifying the server certificate, even though a CA certificate for that endpoint is available in the installation manifest. A network attacker can terminate the TLS connection, harvest the Basic-auth credentials, and read the rendered-templates archive containing every bootstrap secret for the new BOSH Director, then replay the credentials against the real VM’s agent for root code execution.
Affected versions: bosh-cli versions prior to v7.10.4.

Severity: 8.9 | HIGH
