CVE-2026-47828: Missing TLS Certificate Verification in BOSH CLI Allows Root Code Execution via Man-in-the-Middle Credential Replay
- Severity: high (CVSS 8.8 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-07-09 · updated 2026-10-25
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.
Affected products
- CloudFoundry Foundation bosh-cli: before 7.10.4 — fixed in 7.10.4
How to fix
Upgrade to a fixed version: CloudFoundry Foundation bosh-cli 7.10.4. Check the vendor advisory for mitigations.
