Summary
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.
Mitigation
Upgrade to a fixed release: 7.10.4. That is the remediation for this advisory.
The vendor advisory may list additional interim mitigations or workarounds not captured here — review it before change work.
