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

Quick assessment

Affected
BOSH-Ecosystem / BOSH (bosh-cli) bosh-cli
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

CloudFoundry bosh-cli是CloudFoundry基金会的一款命令行界面工具。 CloudFoundry bosh-cli 7.10.4之前版本存在加密问题漏洞，该漏洞源于未验证TLS服务器证书，可能导致网络攻击者通过中间人攻击终止TLS连接、窃取基本身份验证凭据、读取包含BOSH引导秘密的渲染模板存档，并通过凭据重放实现root代码执行。

Vulnerability Title
Missing TLS Certificate Verification in BOSH CLI Allows Root Code Execution via Man-in-the-Middle Credential Replay
Source: CVE Program / CVE List V5
Vulnerability 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.
